  2003-10-05, v2.83

  Initially, installation of MythTV seems like a huge task.  There are
  lots of dependencies, and various distributions seem to do the same
  thing different ways.  This document will attempt to give general
  installation instructions, as well as including distribution-specific
  instructions where necessary.

  [1m2.  Introduction.[0m

  This HOWTO document will focus on manually building MythTV in a North
  American environment. If you have installation instructions for a
  different region or Linux distribution, please send them to the author
  so that it can be included in other versions of this document.

  Hans Kruse has setup a website that focuses on running MythTV in a
  non-North American environment.  See the website at
  http://mythtv.nicenemo.net <http://mythtv.nicenemo.net>.

  Pre-compiled binaries are available for a number of distributions.
  See section ``Software::Pre-compiled packages'' for more information.

  Custom mini-distributions are also available to make it easier to
  install MythTV.  A mini-distribution removes many of the "general
  purpose" workstation / server software packages that may be installed
  by default if you use one of the big-name OS packages.

  See http://linpvr.org/ <http://linpvr.org/> if you'd like to install
  MythTV onto a VIA Epia M machine.

  See http://mysettopbox.tv <http://mysettopbox.tv> if you'd like to
  install a custom version of Knoppix optimized for MythTV.

  [1m3.  Checking prerequisites.[0m

  You must ensure that any firewalls (either hardware, or a software
  firewall installed by your distribution) will not block access to the
  ports that will be used by the MythTV clients and servers on the
  "inside" LAN.  The ports for MySQL (TCP port 3306) and mythbackend
  (TCP ports 6543 and 6544) must be open.  It is [4mstrongly[24m recommended
  that you do [4mnot[24m expose the MythTV and MySQL ports to the Internet or
  your "Outside" LAN.


  [1m3.1.  Hardware.[0m

  Hardware selection is a complex topic, one this HOWTO will only
  discuss briefly and in general terms. The following subsections offer
  some general guidance but stop short of offering specific
  recommendations.

  For more detail about actual configurations that others have used,
  Mark Cooper has setup a hardware database at
  http://pvrhw.goldfish.org/ <http://pvrhw.goldfish.org/>. The website
  will let you browse what other users have reported as their hardware
  configuration, and how happy they are with the results.

  If you have specific questions about the suitability of specific
  hardware choices, you can consult the archives of the mythtv-users
  mailing list at (url url="http://www.gossamer-
  threads.com/archive/MythTV_C2/Users_F11/" name="http://www.gossamer-
  threads.com/archive/MythTV_C2/Users_F11/"> or post a question to the
  list.

  [1m3.1.1.  CPU Type and Speed[0m

  Selection of CPU type and speed is one of the trickiest elements of
  hardware selection, mainly because there are so many tradeoffs which
  can be made.  For example, if you have plenty of CPU, you can use
  higher bitrates or capture sizes, etc.

  MythTV has two modes of operation.  First, it can function as a
  software video encoder, which means that it uses a fairly generic
  "dumb" video capture card to get frames of video, encodes them using
  the CPU on your motherboard and writes them to disk.  High-end video
  capture cards and devices like the Tivo and ReplayTV have dedicated
  encoder chips which use specialized hardware to convert the video
  stream to the MPEG-2 format without using the motherboard CPU.  The
  main CPU has the responsibility of running the Operating System and
  reading and writing the encoded frames to the disk.  These tasks have
  fairly low CPU requirements compared to encoding video, which is why a
  device like a Series 1 Tivo can run with only 16MB of RAM and a 54MHz
  CPU.

  There are many variables that go into the question: "How fast a CPU do
  I need to run MythTV"?  Obviously, the faster your CPU, the better
  your experience will be with MythTV.  If you are using the software
  MPEG-4 encoder and performing the "Watch TV" function, where the CPU
  is both encoding and decoding video simultaneously to allow Pause,
  Fast Forward and Rewind functions for live TV requires more CPU then
  just encoding or decoding.  MythTV also supports multiple encoder
  cards in a single PC, thereby increasing the CPU requirements if you
  plan on simultaneously encoding multiple programs.  As a general
  guideline, plan on 1GHz per encoder.

  Here are a few data points:

  +o  A PIII/733MHz system can encode one video stream using the MPEG-4
     codec using 480x480 capture resolution.  This does not allow for
     live TV watching, but does allow for encoding video and then
     watching it later.

  +o  The developer states that his AMD1800+ system can [1malmost [22mencode two
     MPEG-4 video streams and watch one program simultaneously.

  +o  A PIII/800MHz system with 512MB RAM can encode one video stream
     using the RTJPEG codec with 480x480 capture resolution and play it
     back simultaneously, thereby allowing live TV watching.

  +o  A dual Celeron/450MHz is able to view a 480x480 MPEG-4/3300kbps
     file created on a different system with 30% CPU usage.

  +o  A P4 2.4GHz machine can encode two 3300Kbps 480x480 MPEG-4 files
     and simultaneously serve content to a remote frontend.

  The second mode of operation is where MythTV is paired with a
  hardware-based video encoder, such as a Matrox G200 or a Hauppauge
  WinTV-PVR-250/350.  In this mode, because the video encoding is being
  done externally, the CPU requirements are quite low.  See the ``Video
  Capture Device'' section for details.


  [1m3.1.2.  Memory[0m

  A MythTV host that is both a backend and a frontend and using software
  encoding with a single capture card should run adequately in 256MB of
  RAM.  Additional RAM above 256MB will not necessarily increase
  performance, but may be useful if you are running multiple encoders.


  [1m3.1.3.  Hard Disk(s)[0m

  Encoded video takes up a lot of hard disk space. The exact amount
  depends on the encoding scheme, the size of the raw images, and the
  frames per second, but typical values for MythTV range from 700
  megabytes/hour to 2 gigabyte/hour for MPEG-4 and larger for MPEG-2 and
  RTJPEG.
  [1mNOTE[22m:  You [4mmust[24m use DMA for hard drive access to prevent choppy or
  jittery video.  Red Hat Linux 8.0 apparently does not enable DMA at
  boot time.  See the Troubleshooting Section for ``instructions'' on
  how to do this.

  Writing video to disk is sensitive to timing issues; RTJPEG requires
  less CPU with the tradeoff being larger files and needing to write to
  the disk faster.  MPEG-4 requires more CPU, but the files are smaller.
  At the default resolution, MPEG-2 creates the largest files of all
  with almost no CPU impact.

  See the Troubleshooting ``section'' for more information.


  [1m3.1.4.  Filesystems[0m

  MythTV creates large files, many in excess of 2GB.  You [4mmust[24m use a
  filesystem that will allow you to create large files.  Filesystems
  known to have problems with large files are FAT and FAT32.

  Because of these large files, it may be useful to plan for future
  expansion right from the beginning.  If your case and power supply
  have the capability for additional hard drives, read through the
  ``LVM'' and ``Advanced Partition Formatting'' sections for some
  pointers.


  [1m3.1.5.  Video Capture Device[0m

  In order to watch live TV, MythTV will need one or more video capture
  devices with Linux drivers.  For a list of video capture cards known
  to work with Linux, please see
  /usr/src/linux/Documentation/video4linux/bttv for a partial listing;
  even if your specific card is not listed, it may be that the vendor is
  actually using a standard reference design and placing their own name
  on it.  See the video4linux mailing list
  (https://listman.redhat.com/mailman/listinfo/video4linux-list
  <https://listman.redhat.com/mailman/listinfo/video4linux-list>) for
  more information and for specific hardware questions.

  The most common inexpensive cards available use the Bt848 or Bt878
  video capture chip; examples are the "Hauppauge WinTV Go" card and the
  "AverTV Desktop PVR" card, both of which use the bttv kernel module.


  ______________________________________________________________________
  NOTE:  The ATI TV Wonder series and the ATI All-in-Wonder series of cards
  are not the same.  The All-in-Wonder cards will not work with MythTV.
  ______________________________________________________________________



  Newer cards may use the CX23881 series of chips; a driver is available
  at http://bytesex.org/cx88/ <http://bytesex.org/cx88/>.

  After you have installed a suitable capture device, you can check that
  the kernel sees it with lspci. Look for an entry labeled "Multimedia
  video controller". To get more detailed information about the card,
  use lspci -v or lspci -vv.  Ensure that your system is loading the
  bttv modules by typing:


       # lsmod |grep bttv



  You want to see the bttv module listed.

  While inexpensive video-capture cards just capture raw frames, leaving
  encoding to software, some higher-end cards incorporate hardware-level
  encoding. Using either a G200 MJPEG encoder card, or a WinTV-PVR-250
  or 350 from Hauppauge and the driver from the IvyTV project
  http://ivtv.sourceforge.net/ <http://ivtv.sourceforge.net/> will allow
  you to use dedicated hardware encoders rather than your CPU. Release
  0.11 of MythTV is able to use the PVR-250/350 cards as an input device
  for live TV and for scheduled recordings.  Using the onboard MPEG-2
  encoder drastically reduces the CPU requirements for encoding.

  Here are some data points for encoding:

  +o  A Celeron 450 uses 2% CPU for encoding a 480x480 16Mbps MPEG-2
     stream.

  Here are some data points for decoding:


  +o  An Athlon 1800XP can decode a 720x480 8Mbps MPEG-2 file using 10%
     CPU

  +o  An Athlon 1GHz can decode a 720x480 16Mbps MPEG-2 file using 30-50%
     CPU, can decode a 480x480 16Mbps MPEG-2 using 30% CPU and
     approximately 30% for Live TV at 416x480.

  +o  A P3-550 can decode a 480x480 16Mbps MPEG-2 file with 55% CPU.

  +o  A Celeron 450 (no SSE) can decode a 480x480 16Mbps MPEG-2 file with
     80% CPU.

  See the ``Hauppauge PVR-250/350 hardware MPEG-2 encoder.''  section
  for information on installing a PVR-250 on Mandrake 9.1.

  [1mNOTE[22m: The ATI All-in-Wonder cards (which are not the same as the ATI
  TV Wonder, TV Wonder VE or TV Wonder Pro) [4mwill[24m [4mnot[24m work as a MythTV
  capture device, as the GATOS <http://gatos.sourceforge.net> drivers
  that are available provide only a limited subset of the V4L API.  The
  TV Wonder series of cards are supported by the Bt8x8 Video4Linux
  driver.


  [1m3.1.6.  Sound card[0m

  The system needs a sound card or an onboard equivalent on the
  motherboard to play back and in most cases, to record sound. Any sound
  card that can be operated by the ALSA (Advanced Linux Sound
  Architecture) kernel modules will work with MythTV.  However, some
  cards and drivers will provide better quality or compatibility than
  others.  In particular, many audio devices included on motherboards
  can be problematic.

  The usual practice for capturing the audio associated with the video
  is to run a cable from an audio output on the video capture card to
  the Line input on a sound card. However, some video capture cards
  provide onboard audio capabilities that work with the kernel btaudio
  module instead, thereby eliminating the need for a cable.  This is
  useful if you will be using multiple capture cards in a single
  chassis, since each capture card will not need its own sound card.
  Note that a separate sound card is still required for playback when
  using btaudio, and that often the audio recorded in this way will be
  mono only.  See the ``btaudio'' section for more information.

  [1mNOTE[22m:  The PVR-250/350 does not require a sound card for audio
  capture.
  [1mNOTE[22m:  Plugging a Line-level device into the Mic input is not
  recommended.  Line-level devices have higher volatages and can damage
  the soundcard.  In addition, even if it doesn't break your card, you
  will be getting Mono sound.  See the Linux MP3 HOWTO at

  [1m3.1.7.  Video Display Card[0m

  MythTV will work with just about any video card.  However, it is
  highly recommended that you use a card which supports XVideo (XV)
  extensions. If your card does not support XV, color conversion and
  scaling will be performed by your CPU rather than the video card.
  This is very CPU and memory intensive and will often result in dropped
  frames and a corresponding degradation of quality.  Check the XFree86
  documentation for details if you are uncertain about your preferred
  card.  You may also run xvinfo; look for your video card to be listed
  as one of the adapters.


  If you want to use MythTV with a standard television, you will need a
  physical connection from your video card to your TV set, which can
  either be a TV-out port on the card itself, or an external adapter
  that converts the VGA signal to an appropriate video signal.
  "Appropriate" depends on a number of factors, such as video standard
  (NTSC vs PAL) type of input connection (Composite vs SVideo), etc.

  Note that with some video cards and X drivers, Xvideo extensions are
  only supported on the VGA output, and not on the TV output.


  [1m3.1.8.  Cards with TV out[0m

  The next section deals with a number of cards that are known to have
  TV-out ports.  The list is unlikely to be complete, so if you know of
  others, please post a message to the mythtv-users mailing list so the
  information can be included in future versions of the HOWTO. The list
  is organized by manufacturer.

  Reports here are based on what users of the cards have posted on the
  mythtv-users mailing list, so if you need configuration details,
  please search the archives at http://www.gossamer-
  threads.com/archive/MythTV_C2/Users_F11/ <http://www.gossamer-
  threads.com/archive/MythTV_C2/Users_F11/> using the card name in your
  search string.


  [1m3.1.8.1.  ATI[0m

  ATI makes many cards with TV-out capability, but ATI offers no
  official support for their use with Linux. The standard XFree86 ati
  driver does not support TV-out.

  The enhanced ati.2 X driver created by the GATOS
  http://gatos.sourceforge.net <http://gatos.sourceforge.net> project
  offers some support for TV-out, but only in its "experimental"
  version, available through CVS. There have been reports from people
  who say they have made this driver work with one or another ATI card.
  For example, Bruce Markey  <mailto:bjm@lvcm.com> writes (on the
  mythtv-users mailing list): "I got this to work. You can quote me on
  that. I've used TV-out on several models of ATI cards both All-In-
  Wonder and regular cards with TV-out." See the "Adventurous Setup"
  section of http://gatos.sourceforge.net/watching_tv.php
  <http://gatos.sourceforge.net/watching_tv.php> for details. Also see
  http://www.retinalburn.net/linux/tvout.html
  <http://www.retinalburn.net/linux/tvout.html> for more information.

  Specific cards:

  +o  ATI Rage II+DVD (Mach 64). Ports not described. Reported to work,
     but no details reported.

  +o  Rage 128 VIVO. Ports not described. Reported to work, but no
     details reported.

  +o  Radeon 7500. Ports not described. Reported to work, but no details
     reported.


  [1m3.1.8.2.  Matrox[0m

  The standard Matrox driver included with XFree86 does not support TV-
  out.

  Older Matrox cards can be used with a proprietary X driver provided by
  Matrox, and it does simultaneously support TV out and XVideo on some
  cards.  See http://www.matrox.com/mga/support/drivers/files/lnx_21.cfm
  <http://www.matrox.com/mga/support/drivers/files/lnx_21.cfm> for
  details.

  Newer Matrox cards can be run with a set of kernel patches (for kernel
  2.4.19) and a customized X driver, but this arrangement does not
  support XVideo on TV-out. See
  http://www.bglug.ca/matrox_tvout/g450_tvout_howto.html
  <http://www.bglug.ca/matrox_tvout/g450_tvout_howto.html> for details.

  Specific cards:

  +o  Matrox G400 AGP. Uses external adapter to provide Composite and
     SVideo ports. Reported to work with the proprietary Matrox X
     driver.

  +o  Matrox Millennium 450GX AGP. Uses external adapter to provide
     Composite and SVideo ports. TV-out implementation does [4mNOT[24m support

  [1m3.1.8.3.  nVidia[0m

  Some nVidia cards with TV-out can be run using the standard nv driver
  in XFree86, combined with the userspace application [1mnvtv [22mto control
  the TV-out port. See http://sourceforge.net/projects/nv-tv-out/
  <http://sourceforge.net/projects/nv-tv-out/> for details.  Recent
  versions of the nVidia driver have better support for overscan and
  other features useful with TV-Out, so the [1mnvtv [22mapplication may not be
  required.

  Some nVidia cards can be run with a proprietary nVidia X driver made
  available by nVidia. See http://www.nvidia.com/view.asp?IO=linux
  <http://www.nvidia.com/view.asp?IO=linux> for more information.

  Specific cards:

  +o  GeForce4 MX440-SE AGP. Has Composite and SVideo ports. Works using
     the nVidia X driver.
  +o  GeForce2 GTS 64 MB DDR 4x AGP. Has SVideo port. Works using the
     nVidia X driver. Reportedly works using the nv driver plus nvtv.

  +o  GeForce4 MX420 PCI (BFG Asylum). Has SVideo port.


  [1m3.1.8.4.  Savage[0m

  The standard savage X driver supports TV out on some Savage cards.
  Unfortunately, XVideo support for the Savage 2000 card (a very common
  and inexpensive Savage card with TV out) is broken. See
  http://www.probo.com/timr/savage40.html
  <http://www.probo.com/timr/savage40.html> for details.

  Specific cards:

  +o  Savage 2000 AGP. Has Composite and SVideo ports. Does not support
     XVideo.

  +o  S3 Savage IX 8MB AGP. Has SVideo output. Reported to work.


  [1m3.1.8.5.  Other Options[0m

  Some devices with onboard TV-out capability, such as XBoxes converted
  to Linux and some laptops, can be used as MythTV frontends to display
  on a television screen. Please consult the mythtv-users mailing list
  for messages that report the details of these special arrangements.


  [1m3.1.9.  External Adapters[0m

  External adapters convert standard VGA output to a form suitable for
  display on a television. The output format varies by region, since
  different countries have different TV standards. People on the mythtv-
  users list have mentioned these adapters:


  +o  AITech Web Cable Plus, powered by external transformer or takes
     power from PS/2 keyboard connector, support resolutions up to
     1024x768, outputs composite and SVideo, provides position
     adjustment.

  +o  Averkey lite, powered by a USB port, has Composite, SVideo, YPbPr
     outputs; pan, brightness, overscan/underscan controls; supports up
     to 1024x768 outputs; and supports PAL and NTSC.

  +o  ADS TV Elite XGA

  +o  AverKey iMicro (comments are generally favorable)

  +o  AITech Web Cable (comments are generally unfavorable, different
     than the "Plus" version above)

  [1m3.2.  Software.[0m

  There are a few ways of installing programs on Linux systems; you can
  either use a pre-compiled package, or install from a tarball after
  satisfying any prerequisites.

  [1mNOTE[22m: you must have the MySQL database software installed on a system
  to store the master database.  This does not necessarily mean that
  MySQL must run on one of the MythTV boxes.
  [1m3.2.1.  Pre-compiled packages.[0m

  A number of people have created pre-compiled packages for MythTV that
  may make your installation easier.

  [1mBIG FAT WARNING[22m:  This HOWTO assumes that you have [4mnot[24m installed
  MythTV from a package.  All example command lines and file locations
  are based on the MythTV tarball defaults.  Some packagers have
  modified the filenames, binaries and file locations to match what is
  commonly found in that distribution.  Any issues with MythTV installed
  via a pre-compiled package [1mMUST [22mbe raised with the packager.

  If you use any of the pre-compiled packages you may not need to
  perform any additional configuration steps in this HOWTO.  The next
  logical step is ``configuring MySQL'', which you may or may not have
  to perform.  See your package documentation.


  [1m3.2.1.1.  Red Hat Linux 9[0m

  Red Hat Linux 9 packages for MythTV and most of its add-on modules and
  some themes have been packaged by mailto:Axel.Thimm@physik.fu-

  http://atrpms.physik.fu-berlin.de/topic/multimedia/
  <http://atrpms.physik.fu-berlin.de/topic/multimedia/>. All of the
  prerequisites for MythTV (such as XMLTV) are available as RPM
  packages. If you have problems with the RPMs, please send him email
  directly.

  Given the large number of dependent RPMs you are advised to use tools
  like apt or yum for automatic retrieval and installation of the
  required RPMs.  (http://atrpms.physik.fu-berlin.de/install.html
  <http://atrpms.physik.fu-berlin.de/install.html>) In this case a
  special meta-package called mythtv-suite will allow you to install all
  of MythTV and its add-ons, plus all dependencies.

  If you don't have [1mapt [22mor [1myum [22mon your machine, download and install the
  atrpms-kickstart package <http://atrpms.physik.fu-
  berlin.de/dist/rh9/atrpms-kickstart/>.  Install the package with:

  Then update your [1mapt [22mpackage listings:


       # apt-get update



  And finally:

  These steps however, do NOT perform the installation of any drivers
  required for [1mALSA[22m, capture cards, [1mlirc[22m, etc., nor do they set up your
  MythTV database. Check ATrpms <http://atrpms.physik.fu-

  available at
  http://dijkstra.csh.rit.edu/~mdz/debian/dists/woody/mythtv/
  <http://dijkstra.csh.rit.edu/~mdz/debian/dists/woody/mythtv/> (for
  Debian 3.0/woody) and
  http://dijkstra.csh.rit.edu/~mdz/debian/dists/unstable/mythtv/
  <http://dijkstra.csh.rit.edu/~mdz/debian/dists/unstable/mythtv/> (for
  unstable).  Be sure to use the appropriate packages for your system;
  the woody packages cannot be installed on unstable, nor vice versa.
  Installation instructions can be found on those pages as well.  All of
  the prerequisites for MythTV are available as Debian packages, most of
  them from the official Debian archive.


  If you are running woody, be sure to follow the instructions on the
  above page to ensure that the MySQL server starts up immediately after
  it is installed.  If you are running unstable, this is the default
  behavior.


  The Debian packages are configured such that MythTV programs should be
  run as the mythtv user, which is automatically created during
  installation.  This user has access to write new recordings to disk in
  the default directory, read and write the database, access the audio
  and video devices, and everything else that MythTV needs to do.


  See /usr/share/doc/[4mpackagename[24m/README.Debian for more information,
  including copies of the MythTV documentation.  The mythtv-doc package
  contains a copy of this HOWTO in /usr/share/doc/mythtv-doc.


  [1m3.2.2.  Manual installation[0m

  You may use the graphical tools that come with your distribution, or
  you can use command-line utilities.  Either system will get the job
  done, and it all depends on your comfort level with Linux.

  In order to compile MythTV, we need to make sure that the software it
  needs is installed.  As of 2003-03-15, this list includes [1mmysql[22m, [1mgcc[22m,
  [1mfreetype2-devel[22m, [1mXFree86-devel[22m, [1mqt-devel [22mand [1mlame[22m.  If you're going to
  use a remote control with MythTV, you're going to need the [1mcdialog[0m
  package in order to compile [1mlircd [22mif your distribution doesn't have a
  pre-packaged [1mlirc[22m.  If you are using [1mXMLTV [22mas a grabber, you will need
  [1mperl[22m.

  ______________________________________________________________________
  NOTE:  Qt v3.1 is recommended, but not required.

  NOTE:  If you are going to be using RPMs to install various
  components, you should be aware that not all packages include the necessary
  headers for compiling packages.  If you're having trouble compiling, ensure
  that you've installed the -devel version of a prerequisite.

  NOTE:  Other than where noted, Mandrake 9.1 users may follow the
  Mandrake 9.0 instructions.
  ______________________________________________________________________



  There appears to be issues with ALSA and simultaneously recording and
  playing sound, which is a core requirement for MythTV.  If you are not
  running ALSA 0.9.0rc6 or higher and experience lock-ups of your system
  when trying to use MythTV, then please check the main ALSA website and
  upgrade to the latest version, or see if your distribution has already
  packaged the latest ALSA drivers.


  [1m3.2.3.  Graphical installation tools.[0m

  [1m3.2.3.1.  Mandrake 9.0[0m

  On systems running KDE, a tool which will allow you to see what
  packages are available and if they're installed on your system can be
  accessed by clicking K->Configuration->Packaging->KPackage

  While the graphical tools are nice, the command line tool is actually
  easier to use.  It's strongly recommended that you use the command
  line tool.

  There are many inter-related modules, so make sure that you've got the
  main package for each one, and not a sub package for an unrelated
  item.  For example, there are many modules that have "perl" in them;
  some are a part of the apache web server, others are a part of the
  perl distribution.  In each case, we're looking to make sure that the
  primary module is getting installed.

  Click the magnifying glass or press [1mCTRL-F [22mand enter "perl" as your
  search term.  You should find it under the "Perl" folder.  You need at
  least the perl 5.80 base package installed.  If not, click on the
  "Mark" button.

  If you are going to be installing mysql on this system, search for
  mysql - it should be under "Databases".  Make sure that mysql and
  mysql-clients are installed.  If not, click on "Mark".

  Search for gcc.  You're going to need gcc and gcc-c++ installed.

  Search for freetype2.  Make sure that you've got freetype2 and
  freetype2-devel installed.

  Search for XFree86-devel.

  Finally, check for qt.  You'll need libqt3-devel (under folder "KDE
  and Qt") and libqt3 ("Libraries").


  ______________________________________________________________________
  NOTE for Mandrake 9.1 users:  Mandrake 9.1 has removed the MySQL modules
  from the default installation.  Ensure that you install libqt3-mysql.
  ______________________________________________________________________

  Make sure that cdialog is installed if you want to use MythTV with a
  remote control if you need to compile [1mlirc [22mfrom source.

  alsa-utils is needed for setting the volume.  MythTV now has native
  volume support, but you may have a special configuration that
  necessitates an external program to adjust your volume settings.  If
  this is the case, then you can disable native volume support.

  If you marked anything to install, click on Install Marked.  Click
  "Yes" or OK if you get a message about satisfying dependencies.


  [1m3.2.3.2.  Red Hat Linux 8.0[0m

  Red Hat Linux 8.0 does not have the same graphical package manager
  used by other distributions, so you will need to use Red Hat's package
  manager.  This is the same utility you saw upon installation from the
  Red Hat Linux 8.0 installation CD, and it allows you to select
  packages at installation time, or once the system is up and running.
  You can access this program by selecting

  RedHatMenu>System Settings>Packages



  If you did a typical Desktop install of Red Hat Linux 8.0 make sure
  you have selected:


  +o  KDE Desktop Environment

  +o  SQL Database Server -  you will have to click on "details" and make
     sure "mysql-server" is checked.  (only required on the master
     system)

  +o  Development Tools

  +o  X Software Development

  +o  KDE Software Development

  +o  Kernel Development

  Click Install to continue.

  You can not install qt-MySQL, a necessary prerequisite, graphically.
  To install this package using the command line do



       $ up2date --solvedeps qt-MySQL



  [1mNOTE[22m:  ensure that the correct symlinks have been created for the
  XFree-86 development libraries:



       # ln -s /usr/X11R6/lib/libXext.so.6 /usr/X11R6/lib/libXext.so

  [1m3.2.4.  Command-line installation.[0m

  This section details the various methods for installing prerequisites
  from the command line.


  [1m3.2.4.1.  Mandrake[0m

  [1murpmi [22mis the simplest tool for installation of packages from the
  command line, but properly configuring it can be difficult.  The
  following website http://plf.zarb.org/~nanardon/urpmiweb.php
  <http://plf.zarb.org/~nanardon/urpmiweb.php> will allow you to choose
  a mirror site and then present the command-line configuration text for
  that mirror.  You will most likely need to add a "Contrib" mirror to
  your setup.  If you add a site from the "Penguin Liberation Front",
  you will be able to load the lame library without compiling from
  source.


  [1m3.2.4.1.1.  Special instructions for Mandrake 8.2[0m

  Mandrake 8.2 does not have a pre-packaged libqt3-devel, so you must
  compile and install this manually.  The following command will install
  the prerequisites for qt3, so don't skip this step.  The simplest tool
  for installing packages from the command line is urpmi.

  Open a shell, and execute the following.  You may get asked a number
  of questions regarding dependencies.  It's best to answer "YES".



       $ urpmi mesa-common-devel libmng1-devel mysql-devel libunixodbc2-devel
       $ urpmi postgresql-devel xfree86-static-libs



  Once all of the prerequisites have been installed, the next step is to
  obtain and compile the source RPM.

  Go to http://www.rpmfind.net <http://www.rpmfind.net> and search for
  qt3.  There will be a number of different versions available.  As of
  2002-12-02, the latest version for Mandrake is called
  qt3-3.0.5-7mdk.src.rpm. Unless you are running [1mMandrake Cooker [22m(the
  beta version of the next release of Mandrake), make sure to download
  the standard "Mandrake" release.  Download the .src.rpm file to a
  directory that you can find.


       $ su
       # cp qt3-3.0.5-7mdk.src.rpm /usr/src/RPMS/SRPMS
       # cd /usr/src/RPMS/SRPMS
       # rpm --rebuild qt3-3.0.5-7mdk.src.rpm
       # cd ../RPMS
       # ls -l



  The "ls -l" command will show you a directory listing.  There should
  be two files, one will be named "qt3" and the other will be
  "qt3-devel".  The full filenames will vary, so one you know the file-
  name, you can install them with



  # rpm -Uvh [filename1]
  # rpm -Uvh [filename2]



  Once this has completed (it can take a while, so please be patient),
  continue by following the Mandrake 9.0 instructions.


  [1m3.2.4.1.2.  Mandrake 8.2 and 9.0[0m

  The simplest tool for installing packages from the command line is
  [1murpmi[22m.

  Open a shell, and execute the following, all on the same line. You may
  get asked a number of questions regarding dependencies.  It's best to
  answer "YES".


       $ su
       # urpmi mysql gcc gcc-c++ freetype2-devel cdialog alsa-utils
       # urpmi XFree86-devel perl



  ______________________________________________________________________
  NOTE for Mandrake 8.2 users: do not execute the following
  command.  You've already manually installed the files in the previous
  section.
  ______________________________________________________________________



       # urpmi libqt3-devel



  ______________________________________________________________________
  NOTE for Mandrake 9.1 users: execute the following command.

  # urpmi libqt3-mysql
  ______________________________________________________________________


  However, you might get this when you execute the command above:


       [root@pvr root]# urpmi mysql gcc gcc-c++ freetype2-devel libqt3-devel alsa-utils XFree86-devel perl
       everything already installed



  In that case, you're ready to move to the next ``section''.

  [1m3.2.4.2.  Red Hat Linux 8.0[0m

  [Please submit instructions]


  [1m3.2.4.3.  Gentoo.[0m

  If Qt has not been installed on your system: Edit /etc/make.conf and
  locate the "USE" variable. If the line is commented out, remove the
  comment. The line should have at least:


       USE="mysql alsa"



  Next you need to build Qt. If you don't plan on using the ebuilds as
  described in the Gentoo section then you also need to install lame.


       # emerge lame mysql qt



  If you have already installed Qt: you will need to rebuild because the
  default installation doesn't include mysql support, a requirement for
  MythTV.  To enable SQL support, add "mysql" to your USE variable in
  /etc/make.conf and rebuild Qt by running


       # emerge qt



  All the necessary files will be downloaded and built. Even on a fast
  machine this may take a lot of time if you need to do a full Qt build.


  [1m4.  System Configuration Requirements for Compiling MythTV[0m

  Before you compile MythTV from the current source tarball or from CVS,
  you may need to modify your system configuration in a few ways.

  In general, if you install MythTV from pre-packaged binaries for your
  Linux distribution/version, you don't need to be too concerned about
  the issues in this section of the HOWTO - the install script for the
  packages should take care of them. However, this section is still
  recommended reading which may help if the packager skipped a step in
  their packaging.


  [1m4.1.  Software requirements for compiling MythTV[0m

  [1m4.1.1.  General requirements[0m

  MythTV is written in C++ and requires a fairly complete, but standard,
  compilation environment, including a recent g++ compiler, make, and
  appropriate headers files for shared libraries. Any standard Linux
  distribution should be able to install a suitable compilation
  environment from its packaging system. Section 3.2 of this HOWTO
  provides some details of how to install the required environment for
  many distributions.

  Subsequent sections of this chapter address the few oddities that you
  may have to adjust by hand before you compile MythTV.

  The reference compilation system for MythTV is Debian.

  [1m4.1.2.  Distribution-Specific Notes[0m

  None

  [1m4.2.  Shared-Library Requirements for MythTV[0m

  [1m4.2.1.  Modifying /etc/ld.so.conf[0m

  The runtime manager for shared libraries, [1m/lib/ld.so[22m, gets information
  about the locations and contents of shared libraries from
  /etc/ld.so.cache, a file created by [1mldconfig [22mfrom information in
  /etc/ld.so.conf.  Because MythTV installs some shared libraries in
  /usr/local/lib, that directory needs to be added to the list of
  directories for [1mld.so [22mto search when doing runtime linking of
  programs. You do this, as root, by editing /etc/ld.so.conf, then
  running [1mldconfig[22m. There are many ways to do this; one that works is to
  enter this series of commands:



       $ su -
       # echo /usr/local/lib >> /etc/ld.so.conf
       # /sbin/ldconfig

  [1m4.2.2.  Distribution-Specific Notes[0m

  [1m4.2.2.1.  Red Hat[0m

  It appears that Red Hat Linux 8.0 requires that the [1mldconfig [22mcommand
  be run twice. Red Hat will also frequently "forget" about the path.
  It's recommended to run [1m/sbin/ldconfig [22mafter installing every package.
  Failing that, always run it if you get an unexpected error about not
  finding libraries.

  [1m4.3.  Environment variable Requirements for MythTV[0m

  [1m4.3.1.  General requirements[0m

  [1m4.3.1.1.  QT libraries and binaries[0m

  The compiler needs to be able to locate QT binaries and libraries in
  order to compile MythTV. QTDIR needs to be set and /usr/lib/qt3/bin
  must be added to your path. Your distribution may already be making
  these changes as a part of the installation of the software
  prerequisites detailed earlier.

  One way to do this is as follows:

  Open a shell and execute the following:


       $ echo $PATH
       /usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/usr/games:/usr/lib/qt3/bin:/home/mythtv/bin:/usr/lib/qt3/bin
       $ echo $QTDIR
       /usr/lib/qt3



  You should see a value like /usr/lib/qt3 for QTDIR and
  /usr/lib/qt3/bin should be in $PATH.
  If you don't, do not proceed past this step until you have resolved
  this error. You may need to manually specify the QTDIR and PATH at the
  shell prompt before compiling.

  Also, check that there has been a link created in /usr/lib/qt3/mkspecs
  called default. If not, you'll get errors during the compile. See the
  Troubleshooting Section for more information.

  [1m4.3.2.1.  Mandrake[0m

  The following instructions work for Mandrake 9.0 and 9.1 using [1mbash [22mas
  the shell, and may be applicable for a distribution which uses
  /etc/profile.d.

  As root, create the following file in /etc/profile.d The example
  filename is "mythtv.sh". Use what you feel is appropriate.

  Open a shell, and switch to superuser mode.  [1mNOTE[22m: ^D means press CTRL
  and d at the same time.


       $ su
       # cd /etc/profile.d
       cat > mythtv.sh
       export QTDIR=/usr/lib/qt3
       export PATH=$PATH:/usr/lib/qt3/bin
       ^D

       # chmod a+x mythtv.sh
       # exit
       $ exit



  The last two commands are to exit out of the shell. This way, when you
  next open a shell your new commands will take effect.

  [1m4.3.2.2.  Red Hat Linux 9/8.0[0m

  Red Hat Linux 9/8.0 use a default locale with UTF-8 encoding.
  Date::Manip, a perl module used by XMLTV, is not UTF-8 safe. As a
  result, whenever you run setup or mythfilldatabase you will get a lot
  of UTF-8 warnings. There is an
  http://membled.com/work/patches/DateManip/
  <http://membled.com/work/patches/DateManip/> updated version of
  Date::Manip at the XMLTV site fixing this and other XMLTV related #
  bugs.

  If building from CVS instead of the source package, then the QTDIR
  environment variable must be set when building.  On Debian woody,
  QTDIR should be set to /usr/share/qt.  On Debian unstable, QTDIR
  should be set to /usr/share/qt3.


  [1m5.  Downloading and compiling.[0m

  Get MythTV from the mythtv.org <http://www.mythtv.org> web site.
  There are two installation methods you may choose from.  The first is
  to download the latest release in tarball format and compile.  The
  tarball release of MythTV should work on a wide variety of systems and
  should be the preferred method for new users.  If you wish to use the
  CVS version of MythTV you may obtain it from CVS this way:



       $ mkdir mythtv
       $ cd mythtv
       $ cvs -d :pserver:mythtv@cvs.mythtv.org:/var/lib/mythcvs login
       Logging in to :pserver:mythtv@cvs.mythtv.org:/var/lib/mythcvs
       CVS password: mythtv
       $ cvs -z3 -d :pserver:mythtv@cvs.mythtv.org:/var/lib/mythcvs checkout mythtv



  The other MythTV modules may be downloaded from CVS the same way;
  replace "mythtv" with "mythweather", "mythgallery", "mythmusic", etc.

  If you wish to stay up-to-date with CVS, you may replace "checkout
  mythtv" with update mythtv after you've done your initial download.

  [1mNOTE[22m: If you are going to use CVS to compile MythTV rather than using
  the distribution tarball, it is [1mstrongly [22mrecommended that you join the
  http://www.mythtv.org/mailman/listinfo/mythtv-commits/

  If you've got a system with an AMD K6-2 or a VIA C3 processor, make
  the following change in the settings.pro file.

  Look for

  -march=pentiumpro


  and replace it with

  Recent AMD processors, like the Duron, Thunderbird and Athlon don't
  need this change.

  [1mNOTE[22m:  subsequent configuration steps assume that you are within the
  MythTV directory that you cd'd to above.


  [1m5.4.1.  Frontend-only configuration[0m

  Since MythTV uses a client/server architecture, multiple frontend
  computers can simultaneously access content on a Myth system.  Live
  TV, watching and scheduling recordings, etc. are all possible from
  multiple frontends.

  To get a better picture of what is needed to run a frontend, note the
  following:

  You do NOT need the MySQL server installed on your remote frontend

  You do NOT need XMLTV installed on your remote frontend

  You do NOT need to run the MythTV setup program on your frontend
  machine

  Other than the exclusion of the MySQL server and XMLTV, the MythTV
  compilation procedure is the same as when you're setting up both a
  backend and a frontend.  However, you [4mwill[24m need to install the
  database access libraries.

  Once MythTV is compiled and installed, you must change your
  /usr/local/share/mythtv/mysql.txt or ~/.mythtv/mysql.txt file's
  "DBHostName" field to point to your master backend's IP address.

  Run the MythTV setup program on your master backend. Under the
  "General" menu, change the IP address of the current machine (by
  default, "127.0.0.1") to the real external IP address - 127.0.0.1 is
  the loopback address and no external machine can access it. Change the
  Master Server IP setting to the same IP address as well.


  [1m5.5.  Gentoo.[0m

  Installation of MythTV on Gentoo consists of simply emerging the
  desired ebuild because all of the packages are now part of the

  After installing mysql you need to initialize the database by running

  [1m6.4.  Setting up the initial database.[0m

  This step is only required on the system maintaining the database,
  which may or may not be one of your MythTV boxes.  If the database is
  on a non-MythTV machine you'll need to copy the database/mc.sql file
  to it.

  To setup the initial mysql databases:


       $ cd database



  [1m6.4.1.  Mandrake 9.0 and Red Hat Linux[0m



       $ mysql -u root < mc.sql

  [1m6.4.2.  Debian 3.0[0m

  [1m6.4.3.  Gentoo[0m



       $ su
       # mysql < /usr/share/mythtv/database/mc.sql



  If you've already got a copy of the database installed and need to
  update the schema, use the -f flag to force [1mmysql [22mto continue setting
  up the tables even if they already exist.  By default, [1mmysql [22mwill stop
  at the first error.

  [1mNOTE[22m: It is good practice to set a root password for mysql.
  Instructions for doing so can be found on MySQL's web site at
  http://www.mysql.com/doc/en/Security.html
  <http://www.mysql.com/doc/en/Security.html>.


  [1m6.5.  Upgrading the database[0m

  If you need to upgrade the database, either because you're using the
  CVS version of MythTV, or because you're moving from one release to
  another, you'll need to run the appropriate [1mmysql [22mscript found in the
  database/ directory.  Use the same format as above, replacing "mc.sql"
  with the appropriate .sql file:

  So, if you're upgrading from MythTV 0.10 to 0.11 on a Mandrake system:


       $ cd database
       $ mysql -u root < 0.10-to-0.11.sql



  [1m6.5.1.  Modifying access to the MySQL database for multiple systems[0m

  If you're going to have multiple systems accessing a master database,
  you must grant access to the database from remote systems.  By
  default, the mc.sql script is only granting access to the local host.

  To allow other hosts access to your master database, you can either
  set it up for no security at all, or with more granularity.  Note that
  the "%" is the wildcard character in MySQL.

  [1mNOTE[22m:  The "no security" option is [4mvery[24m dangerous unless you're in a
  controlled environment.

  This example has no security at all, and allows access from any host.



  $ mysql -u root mythconverg
  mysql> grant all on mythconverg.* to mythtv@"%" identified by "mythtv";



  For a more secure setup, you can restrict which machines or subnets
  have access. If you have a complete DNS system operational, you could
  do the following:


       $ mysql -u root mythconverg
       mysql> grant all on mythconverg.* to mythtv@"%.mydomain.com" identified by "mythtv";



  Finally, if you just want to restrict by IP subnet:


       $ mysql -u root mythconverg
       mysql> grant all on mythconverg.* to mythtv@"192.168.1.%" identified by "mythtv";



  [1m7.  Setting up ALSA and the mixer.[0m

  If your video doesn't appear to be in-sync with your audio, it could
  be because you are listening to the real-time audio from your video
  card rather than after it's been processed and synchronized to the
  video by MythTV.  Because MythTV is a personal video recorder, "Live
  TV" isn't really live - to let you pause live TV, MythTV is actually
  encoding the video, saving to disk, and then playing it back.  This
  procedure puts your MythTV "live" TV about 2 seconds behind real-time,
  so it's important that you're not listening to the live audio.
  However, if you're having an issue where the audio and video aren't
  synchronized by small but varying amount, it's most likely because the
  sound driver that you're using doesn't have the DSP_CAP_REALTIME
  capability.  This was the case with ALSA (0.5), but not with newer
  versions (0.9).  See the ``Troubleshooting Audio'' section for more
  information if you're having issues with sound.  Also, ensure that no
  other programs are grabbing the audio output, like [1marts [22mor [1mesd[22m.

  What you need to do is to mute the "line-in" of your sound card and
  also set it as the recording source.

  There are two ways to do this.  Graphically, and from the command
  line.


  [1m7.1.  Graphically setting up the mixer.[0m

  [1m7.1.1.  Mandrake 9.0 and Red Hat Linux[0m

  Open Kmix by clicking K->Multimedia->Sound->Kmix for Mandrake, or

  RedHat Menu>Sound & Video>Volume Control



  Click on Settings->Configure  Make sure that "Tick Marks" and "Show
  labels" have "X"'s in them.  This will make it easier to find the
  correct audio source.  Click OK.

  On the mixer page, look for Line-In on your sound card.  You should
  see two LED's - a green one at the top, and a red one at the bottom.
  The green one at the top is for muting; you want to make sure that the
  green LED is a dark green, meaning that it's "off".  You also want to
  click on the red LED so that it turns bright red, indicating that it's
  "ON"; this insures that the Line-in is used as the source.  Click OK,
  and make sure that you save the settings so that this is your default.


  [1m7.1.1.1.  Using OSS drivers.[0m

  Red Hat Linux 8.0 ships with OSS sound drivers rather than the ALSA
  drivers recommended by the MythTV team. The OSS drivers do work for
  many people, and for many cards. We recommend that you give OSS a try
  since it is already included in Red Hat 8. However, some people report
  problems (sync and jitter) with OSS, and in addition it does not
  support full duplex on some cards.  Full duplex is required if you
  want to record and play sound using just one sound card. ALSA has good
  full duplex support, and also has drivers for some built-in
  (motherboard) sound cards that OSS does not.  Installing ALSA is less
  painful than you might think, so if OSS does not work for you,
  installing ALSA is not too difficult. For those of you who do not wish
  to install ALSA you must do this:

  To configure sound to work with MythTV, select

  RedHat Menu>Sound &
  Video>Volume Control


  (on the far left) is up. Also make sure that the "line in" section has
  "mute" and "record" checked and that the gain is turned up. You may
  have to experiment with volume/gain levels to get the best sound.


  [1m7.1.1.2.  Using ALSA drivers.[0m

  For those of you who do want to install ALSA please follow the
  directions below, compiled with much assistance from Gregorio
  Gervasio.

  First you must find out the name of your driver, which isn't
  necessarily the same as the name of your sound card. Go to
  http://www.alsa-project.org/alsa-doc/ <http://www.alsa-
  project.org/alsa-doc/>, find your sound card on the list and click
  "details". Near the top it will say something like "The module options
  for snd-XXX", where XXX is the name of your driver. In the
  instructions below, replace "XXX" with the name of your driver.

  Download the development release (0.9.x) from the ALSA web site
  http://www.alsa-project.org <http://www.alsa-project.org>.  You need
  at least three files:

  +o  alsa-driver-0.9.x.tar.bz2

  +o  alsa-lib-0.9.x.tar.bz2

  +o  alsa-utils-0.9.x.tar.bz2

  Start with the alsa-driver package:



  $ tar -xjf alsa-driver-0.9.x.tar.bz2
  $ cd alsa-driver-0.9.x
  $ ./configure --with-cards=XXX --with-sequencer=yes
  $ make
  $ su
  # make install
  # ./snddevices
  # exit
  $



  This will compile and install the kernel modules and initialization
  scripts, as well as create device nodes in /dev.

  Install the rest of the packages:


       $ cd ~
       $ tar -xjf alsa-lib-0.9.x.tar.bz2
       $ cd alsa-lib-0.9.x
       $ ./configure
       $ make
       $ su
       # make install
       # exit
       $ cd ..
       $ tar -xjf alsa-utils-0.9.x.tar.bz2
       $ cd alsa-utils-0.9.x
       $ ./configure
       $ make
       $ su
       # make install



  Next, you must edit /etc/modules.conf so that the ALSA modules are
  loaded automatically. The first step is to remove your old OSS
  configuration to ensure that you don't end up with mysterious
  conflicts in the future.  You should end up with a /etc/modules.conf
  file that has this configuration:


       alias char-major-116 snd
       alias snd-card-0 snd-XXX
       # module options should go here
       # OSS/Free portion
       alias char-major-14 soundcore
       alias sound-slot-0 snd-card-0
       # card #1
       alias sound-service-0-0 snd-mixer-oss
       alias sound-service-0-1 snd-seq-oss
       alias sound-service-0-3 snd-pcm-oss
       alias sound-service-0-8 snd-seq-oss
       alias sound-service-0-12 snd-pcm-oss



  "XXX" should be the ALSA driver name for your sound card/chip. In some
  rare cases you need to supply extra options to the driver. These
  options are descried in the "INSTALL" file in the alsa-driver
  directory or at http://www.alsa-project.org/alsa-doc/
  <http://www.alsa-project.org/alsa-doc/>.
  For now we will assume that no extra options are required.  The next
  step is to ensure that the ALSA drivers are started during boot-up.


       $ su
       # cd /etc/rc.d/init.d
       # /sbin/chkconfig --add alsasound



  The next set of instructions will cause the ALSA volume/mixer/etc.
  state to be saved when the machine is shut down properly. Note that
  the mixer settings won't get restored the next time you boot unless
  you ran the shutdown script or you've explicitly saved the state which
  you can do as root with:


       # alsactl -f /etc/asound.state store



  Reboot your machine.  Login and adjust the sound levels using
  "alsamixer".  You should increase the main volume (the first slider)
  and the PCM volume, and unmute them by hitting "m".  For MythTV, if
  your tuner card audio output is patched to the Line-In input of your
  sound card, set the Line input for capture by pressing SPACE at the
  slider and mute it by pressing "M". If you've patched your tuner card
  to the Mic-In port of your sound card, follow the same instructions
  but make sure that you're on the Mic slider.

  Test the driver by playing a simple file:


       $ aplay /usr/share/sounds/info.wav



  If it works, you're done installing ALSA!


  [1m7.2.  Setting the mixer from the command line.[0m

  If you have installed the alsa-utils package, then the [1mamixer [22mprogram
  can be used to setup the mixer.  The "Master" volume setting is only
  required on a frontend machine to ensure that the sound channels are
  unmuted and configured for outputting sound.  The "Line" and "Capture"
  controls are required for your sound card to actually capture audio
  from the external Line-in.  Not all sound cards have a "Capture"
  control, but if yours does and you don't set it then MythTV will not
  capture audio.


  ______________________________________________________________________
  Note the spelling in the following commands.
  ______________________________________________________________________



  $ amixer set Master,0 100%,100% unmute
  $ amixer set Line,0 75%,75% mute captur
  $ amixer set Capture,0 100%,100% mute captur
  $ su
  # alsactl store
  # exit
  $



  If you have multiple sound cards, then use the -c parameter to specify
  which card to adjust.  Note that the first card will be "0", the
  second will be "1", etc.

  That takes care of setting the volume correctly, and the ALSA startup
  script will restore the volume after a reboot.  If you find that your
  sound is distorted, it's possible that the levels in the above
  examples are too high for your particular hardware combination.  Try
  reducing the percentages by 5-10% and checking again.  Once you're
  satisfied, re-run the alsactl store command.

  You may also use the [1malsamixer [22mprogram to set the volume.  First,
  start [1malsamixer [22mfrom the command line.  You should start out on the
  "Master" volume control slider.  Use the up and down cursor to set the
  master volume to around 75%.  Next, use the left and right cursor keys
  to move around on the screen until you find the "Line" slider.  Press
  SPACE to set it as the capture source, set the level to around 50-75%
  and press "M" to mute it.  You can now press ESC to exit out of the
  [1malsamixer [22mprogram.  You can also have MythTV manage all volume and
  mute settings, but this will only affect the "Master" or PCM volume,
  not the capture volume.  See the mythfrontend setup page for options.


  [1m8.  Setting up a remote control.[0m

  MythTV does not have native remote control receiver and decoder
  software built-in.  Instead, remote control functions are implemented
  by cooperating with [1mlirc[22m, the Linux Infrared Remote Control program.
  [1mlirc [22mhandles the IR hardware and passes keystrokes to MythTV, which
  then acts as if the user had pressed the keys on the keyboard.  The
  file keys.txt describes the keys used to control MythTV.

  [1mNOTE[22m:If you are running Mandrake 9.1, you may install [1mlirc [22mby
  executing: # urpmi lirc lirc-remotes and bypass the manual compilation
  steps described below by jumping to the ``Completing the lirc
  install'' section.  See the contrib/mandrake91.etc.sysconfig.lircd
  file for an example of how to configure lircd.

  [1mNOTE[22m:  If you wish to use the remote control that comes with the
  Hauppauge PVR-250/350 cards, you will need to run the lirc 0.7.0pre2
  code.  See the example installation in the "Hauppauge PVR-250 remote
  and MythTV's native LIRC support" ``section''.

  Some IR devices require a kernel recompile, and some don't. However,
  all at least require having the kernel source available as a resource
  for the lirc build process.


  [1m8.1.  Gentoo[0m

  To install lirc on Gentoo, all you need to do is:


       # emerge lirc

  [1m8.2.  Mandrake 9.0[0m

  lircd has two prerequisites:  [1mdialog[22m, available in Mandrake through
  the "cdialog" RPM, and the kernel source.  Mandrake 9.0 is using the
  2.4.19 kernel, so either install the kernel sources from the
  installation CD or go to http://www.kernel.org <http://www.kernel.org>
  and download the full 2.4.19 tar file from
  http://www.kernel.org/pub/linux/kernel/v2.4/
  <http://www.kernel.org/pub/linux/kernel/v2.4/>.


  [1m8.2.1.  Obtaining the kernel.[0m

  Install using urpmi.


       $ su
       # urpmi kernel-source



  [1m8.3.  Red Hat Linux[0m

  You should already have the source from the "Kernel Development"
  package you installed in section 3.2. Ensure that a symlink has been
  created:


       $ cd /usr/src
       $ su
       # ln -s linux-2.4 /usr/src/linux
       # exit



  [1m8.4.  Obtaining and compiling lirc.[0m

  You're going to need to download and compile [1mlircd[22m.  Go to
  http://www.lirc.org <http://www.lirc.org> and download lirc; as of
  2002-11-07, the version available is 0.6.6.  Grab the remotes.tgz file
  as well.


       $ tar -xjf lirc-0.6.6.tar.bz2
       $ cd lirc-0.6.6
       $ ./setup.sh



  You're going to need to know what sort of receiver you have and where
  it's connected.  In the case of the Pinnacle Studio TV card, with the
  IR receiver connected to COM1 (/dev/ttys0), once the configuration
  menu comes up, perform the configuration by going to Driver Configura-
  tion->Other Serial Port Devices->Pinnacle Systems Receiver->OK and on
  the next page select COM1->OK.

  Each remote is different; some remote receivers connect directly to
  your capture card and not to a serial port, so make sure that you've
  got the correct one.


  You then click "Save Configuration and run configure" to continue.

  Make sure you read the last text generated by the configure step. It
  will tell you if you require a kernel recompile, and what the name of
  your kernel module will be (if necessary). For instance a home-built
  receiver may require a kernel recompile, so you would be notified that
  you will have to load the lirc_serial module. If you did not get any
  such messages skip the kernel recompile steps below and go directly to
  making and installing the lirc driver.

  Once the configuration step is complete:


       $ make
       $ su
       # make install
       # chmod 666 /dev/lircd



  At this point, if you're using a serial receiver, check that there's a
  lirc device in /dev:


       $ ls -l /dev/li*
       lr-xr-xr-x    1 root     root            5 Jan 27 09:00 /dev/lirc -> ttyS0
       srw-rw-rw-    1 root     root            0 Jan 27 15:01 /dev/lircd=
       prw-r--r--    1 root     root            0 Jan 27 09:00 /dev/lircm|



  As you can see, there's a link from /dev/lirc to ttyS0, a.k.a. "COM1",
  which is appropriate for the Pinnacle Systems PCTV Pro.  However, you
  may notice something like this:


       crw-------    1 root     root      61,   0 Dec 31  1969 lirc



  Some IR receivers (including some homebrew units) use a character
  device as their data interface as opposed to a link to a serial port.
  If the make install step has created a character device for you, don't
  replace it with a link to a COM port.

  So, if the link or character device was not created (but should have
  been), ensure that you ran the make install step as root.  If it still
  doesn't work, then there are three options.  The first option is to
  re-read the [1mlirc [22mdocumentation to determine whether your IR receiver
  is a character device or should be a link to a serial port and to
  create the link/character device manually.  In this example, the IR
  device is connected to ttyS0.  If it were connected to "COM2", then
  use ttyS1, etc.


       $ su
       # cd /dev
       # ln -sf ttyS0 lirc
       # exit
       $



  [1mNOTE[22m:  The above example assumes that your receiver uses the standard
  serial driver.  Some receivers do not, including receivers that plug
  into a TV capture card.  Check the lirc documentation, but it may be
  necessary to replace the link created above with a a character pipe:


       # mknod /dev/lirc c 61 0



  See the lirc documentation for additional information.  The lirc
  installation [4mshould[24m create this for you, so manually creating it
  indicates that your lirc installation may have other issues.

  The second option is to post your issue to the [4mlirc[24m list, not the
  mythtv-users list.  The lirc programmers will be the ones that can
  assist you best.

  The third option is to dispense with lirc altogether by purchasing an
  IR keyboard (various options exist, although Chicony appears to work
  for some people) and a learning remote control.  The IR keyboard
  receiver plugs into the PS/2 keyboard port on your PC and you would
  train your learning remote to emulate the various keystrokes from
  keys.txt of your IR keyboard.  Using this method removes lirc entirely
  from the picture - your remote will be sending keypresses that your PC
  "sees" on the keyboard port.


  [1m8.4.1.  Recompiling your kernel on Red Hat Linux[0m

  Don't Panic! Red Hat makes a kernel recompile very easy. They provide
  configuration files that make it so you can recompile your kernel with
  Red Hat defaults. And as a side benefit, your kernel will be compiled
  specifically for your architecture. For a more detailed description
  (or if you run into trouble) of how to do this go to
  http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-
  guide/ch-custom-kernel.html
  <http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-
  guide/ch-custom-kernel.html>

  [1mNOTE[22m: Suitable Red Hat kernels for MythTV (i2c update, v4l2 api,
  CONFIG_SERIAL modularized) are available from ATrpms:
  http://atrpms.physik.fu-berlin.de/name/kernel/
  <http://atrpms.physik.fu-berlin.de/name/kernel/>. You will also find
  suitable kernel modules for ALSA, lirc, bttv, ivtv, saa7134 etc.
  there. See also the ``main Red Hat section''.

  For the impatient: Make sure you have an emergency floppy boot disk
  available!


       $ cd /usr/src/linux
       $ su
       # make mrproper
       # cd configs
       # ls



  at this point you must look at the file names and determine which
  config file is right for you. For instance if you have an Athlon XP
  you should choose "kernel-2.4.18-athlon.config" but if you have a dual
  processor P4 you might choose "kernel-2.4.18-i686-smp.config"

  # cp yourconfig.config ../.config
  # cd ../
  # make xconfig



  At this point you will get a graphical configuration utility. All that
  you must do to make lirc work is go to the "character devices" section
  and change "Standard/generic (8250/16550 and compatible UARTs) serial
  support" from "y" to "m". Now if you want you can have a look around.
  For instance, you might wish to turn off ham radio support, or perhaps
  turn off PCMCIA support if you are not on a laptop. But be careful!
  Only change things you know you can change. If you are not sure, just
  stick to the one required change. Click "save and exit".  Next:


       # make dep
       # make clean
       # make bzImage modules
       # make modules_install
       # make install



  if you are using [1mgrub[22m, that should be it, reboot and select your
  custom kernel upon boot. If you are using [1mlilo[22m, change your lilo
  configuration according to
  http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-guide/
  s1-custom-kernel-bootloader.html
  <http://www.redhat.com/docs/manuals/linux/RHL-8.0-Manual/custom-guide/
  s1-custom-kernel-bootloader.html> Remember, if you have any custom
  kernel modules (ALSA, etc) you will have to recompile/reinstall those.


  [1m8.5.  Completing the lirc install.[0m

  [1mNOTE to Mandrake 9.1 users[22m: skip to the manual start paragraph below.

  If the lirc configure program / compile did not mention anything about
  a kernel module, then you are finished. If it did mention a kernel
  module, you must edit the /etc/modules.conf file. Add this line as the
  first thing in the file.  It must come first, or it may not work.


       alias char-major-61 XXX



  replace XXX with the name which you determined earlier, which in this
  example was "lirc_serial"


       $ su
       # modprobe lirc_serial
       # /sbin/ldconfig



  Next, we're going to manually start lircd the first time.  Mandrake
  9.1 users, type: # /etc/rc.d/init.d/lircd start instead of:


  # /usr/local/sbin/lircd



  If this fails, complaining of a missing lircd.conf file, then you must
  find or make one. First look for a premade configuration file at
  http://lirc.sourceforge.net/remotes/
  <http://lirc.sourceforge.net/remotes/>.  Mandrake 9.1 users, look in
  /usr/share/lirc-remotes. If you find one your remotes either on the
  website or in /usr/share, download or copy the file, name it
  lircd.conf and put it in your /etc directory. If you couldn't find
  your remote, you must make your own lircd.conf file.

  To make your own lircd.conf file


       $ irrecord myremote



  Follow the on-screen directions to train your remote and define keys.
  If your remote ends up working well, you should consider submitting
  your lircd.conf file back to the lirc developers. Once finished:


       $ su
       # cp myremote /etc/lircd.conf



  now try to start lircd again:


       # /usr/local/sbin/lircd



  Now, we're going to add the commands necessary for lircd to run each
  time we boot. Mandrake 9.1 users, you can execute:


       $ su
       # chkconfig --level 35 lircd on
       # exit



  All other distributions:


       # cd /etc/rc.d
       # cat >> rc.local
       echo "Starting lircd"
       /usr/local/sbin/lircd
       ^D
       # exit
       $



  This takes care of the lircd portion, which "listens" for the IR
  signals. If everything went well, the install script for lircd put an
  appropriate configuration file for your remote into /etc/lircd.conf
  This file maps the buttons on the remote control to the IR pulses
  coming from the receiver.

  The next step is to convert those signals into something that can be
  used to control MythTV.  MythTV now includes native support for lirc
  and can interact directly with



       $ cd ~/mythtv-0.11/configfiles
       $ cp lircrc.example ~/.lircrc



  or


       $ cp lircrc.example.pinnaclestudiopctv ~/.lircrc



  if you've got a Pinnacle Studio PCTV remote.


       $ irw



  Start pressing the keys on your remote; [1mirw [22mwill print the name of the
  button as it is defined in your /etc/lircd.conf. If you don't see any-
  thing at this point, you need to troubleshoot further by going back to
  the lirc home page and investigating from there.

  If it is working, then press [1mCTRL-C [22mto abort the program.  Once you
  know that your remote is working, you can either recompile MythTV with
  native lirc support (edit the settings.pro file and remove the "#"
  from the lirc option, then make distclean and make) or you need to run
  the [1mirxevent [22mprogram, which takes the key presses and sends them to
  MythTV.  If you use native lirc support, you don't need to run
  [1mirxevent[22m.  If you are going to use irxevent, then you need to run it
  like this:


       $ irxevent &



  If [1mirxevent [22misn't running, then MythTV will not respond to your remote
  control unless you're using native lirc support.


  [1m8.6.  Additional information for lirc.[0m

  Take a look at the lircrc.example files in the configfiles/ directory.
  In my case, (Pinnacle Studio card) the channel up and down functions
  weren't working, due to the fact that the button names were different
  than the default lircrc.example file that came with MythTV.


  The lircrc.example file has this:


       begin
           prog = irxevent
           button = ChannelUp
           config = Key Up CurrentWindow
       end

       begin
           prog = irxevent
           button = ChannelDown
           config = Key Down CurrentWindow
       end



  but the /etc/lircd.conf that comes in the lircd package defines the
  buttons for the Pinnacle Studio PCTV as:


                 channel+                 0x0000000000000017
                 channel-                 0x000000000000001C



  rather than "ChannelUp" and "ChannelDown".  I added the following to
  my /home/[yourusername]/.lircrc file:


       begin
           prog = irxevent
           button = channel+
           repeat = 3
           config = Key Up CurrentWindow
       end

       begin
           prog = irxevent
           button = channel-
           repeat = 3
           config = Key Down CurrentWindow
       end



  which took care of basic functionality.  Because the PCTV Studio
  remote has additional buttons, look at the configfiles/lircrc.exam-
  ple.pinnaclestudiopctv for an example of how to define additional but-
  tons, and how to debug potential button name conflicts between the
  lircrc.example file and how [1myour [22mremote defines the button names.

  By examining the button names defined in /etc/lircd.conf and using the
  [1mirw [22mprogram to make sure that your remote is working, you can create
  the appropriate mappings in .lircrc to get excellent remote
  functionality with MythTV.

  Note the [1mrepeat = [22mparameter.  This informs the irxevent program to
  pass through every third keypress.  By default, lirc will only send
  one keypress to the application, even if you're holding down the key.
  The actual [1mrepeat = [22mnumber will vary from system to system, so
  experiment and see which value works best for you.

  [1m8.7.  Configuring lirc for use with an IR blaster.[0m

  By Carlos Talbot,  <mailto:carlos@talbot.net>

  Lirc has support for various IR transmitters. A popular model is the
  Actisys IR-200L http://store.yahoo.com/snapstreammedia/irblasbun.html
  <http://store.yahoo.com/snapstreammedia/irblasbun.html>. It was
  originally designed for IRDA communication, but can be used to
  transmit A/V remote control codes. By using the lirc SIR driver, this
  device can easily be integrated with MythTV. I have tested this device
  with an AT&T DCT2000 digital cable box but the instructions can be
  used to configure other IRDA devices and A/V remotes.

  Follow the steps in the previous section.  When you run setup.sh,
  select option 1, driver configuration. From here select option 6, IrDA
  hardware.  Select your appropriate device and the corresponding serial
  port, then Save configuration & run configure from the main menu. Once
  configure is done type:


       $ make



  Please note: unlike the Pinnacle receiver above you will be compiling
  lircd in addition to a kernel module for the SIR transmitter.
  Depending on whether you have your serial port driver configured as a
  kernel module you might see the following message during make:


       lirc_sir.c:56:2: warning: #warning
       "******************************************"

  If you do receive this statement make sure to run the [1msetserial[0m
  command before you load the lirc_sir module. Follow this with the
  install:


       $ su
       # make install



  You will notice that lirc installs the kernel module in
  /lib/modules/uname -a/misc.

  The configuration for starting [1mlircd [22mdiffers if you're going to be
  sending and receiving IR versus just receiving.


  # cd /etc/rc.d
  # cat >> rc.local
  echo "Starting lircd"
  setserial /dev/ttySx uart none        # (if required)
  modprobe lirc_sir
  /usr/local/sbin/lircd
  ^D
  # exit
  $



  At this point you have to populate the /etc/lircd.conf file with the
  proper codes for your A/V remote. You should be able to find your
  remote within the lirc remote tar file located at
  http://www.lirc.org/remotes.tar.bz2
  <http://www.lirc.org/remotes.tar.bz2>. In my case I extracted the file
  from remotes/motorola/DCT2000 (gi-motorola-dct2000)

  To test the lirc_sir module you can run [1mirw [22mto verify the codes are
  being received. If everything is configured correctly you should see
  something similar to the following:


       $ irw
       0000000000007ff0 00 1 gi-motorola-dct2000
       000000000000bff8 00 2 gi-motorola-dct2000
       000000000000f7f0 00 ENTER gi-motorola-dct2000



  Once you've verified lirc is working you can press [1mCTRL-C [22mto exit [1mirw[0m
  and configure the channel changing script.

  The path to the channel changing script will need to be entered on the
  mythbackend setup screen for Input Connections.

  This csh script will be called each time MythTV needs to change the
  channel.  Below is a copy of the script followed by the corresponding
  perl script.  Make sure both are in your path. Also make sure you
  leave the #!/bin/csh setting and not change it to Bourne or bash. This
  will create a frustrating symptom to diagnose where MythTV cannot open
  /dev/device. Unlike Bourne or bash, csh scripts automatically close
  parent file descriptors before they start.


       $ cd /usr/local/bin
       # su
       # cat > change_channel.csh
       #!/bin/csh
       echo "changing to $1"
       /usr/local/bin/channel.pl $1 &
       ^D
       # chmod a+x change_channel.csh
       # exit
       $ exit



  See contrib/channel.pl for the actual file.  Copy it to
  /usr/local/bin/


  The last statement within the perl script is the lirc rc command. This
  is the command that transmits the code to your cable/DSS box. Make
  sure to have the IRDA device within a few feet of the box.


  [1m9.  Configuring MythTV.[0m

  By this point, all of the prerequisites have been installed, [1mmysql [22mis
  running and has had its initial database setup.  It's now time to
  configure MythTV.


  [1m9.1.  Configuring the master backend system.[0m

  Open a shell and decide where you will store your video files.  By
  default, MythTV will assume that you will be using /mnt/store/, but if
  this directory doesn't exist, or it exists and you don't have write
  privileges to it then MythTV will fail when you attempt to make a
  recording.  The following example is specific for /var/video, but the
  same instructions would apply if you want to keep the default but
  don't have the directory structure setup yet.  See the ``Advanced
  Partition Formatting'' section for hints on creating a partition for
  MythTV.

  If you create a /var/video subdirectory, change /mnt/store/ to
  /var/video/ in the setup screens.


       $ su
       # mkdir /var/video
       # chmod a+rwx /var/video
       # exit



  The first thing to configure is the master backend system.  If you are
  running multiple backend systems, the master backend will make all
  decisions about which programs will be recorded on which tuners.  If
  you have only one backend, then it will be its own master.

  The master will always choose the first available tuner in the same
  order as you add cards through "setup". In other words, the second
  card you add will only be used when there are two overlapping
  recordings, the third when there are three, and so on. Therefore, you
  will want to have your largest disk space on the master because the
  tuner on the master will always be the first choice. You will then
  want to add your ``other backends'' in the order of your preference
  for recording.

  See ``Advanced Backend Configurations'' for information on configuring
  multiple backend systems in various ways.

  Because MythTV now uses a database to store most configuration
  variables, part of the bootstrap of MythTV is to indicate the location
  of the MySQL database server. If the frontend, backend and MySQL
  database server are all going to be running on the same box, you can
  continue to the next step.  If not, you'll need to edit the
  /usr/local/share/mythtv/mysql.txt file and change the first line to
  the IP address of the database server.  All other configuration is
  within the MythTV GUI screens.

  [1mNOTE[22m:  Users that have been running the frontend and the backend on
  different machines using Red Hat Linux 8.0 have stated that they have
  been having issues with remote access to the MySQL database.  The
  following instructions may or may not work.  Add the following to
  /etc/my.cnf on the backend machine and restart MySQL.


       skip-innodb
       set-variable=thread_stack=256k



  Switch to the setup directory and run the setup program:


       $ cd setup
       $ ./setup



  The backend setup program will start and offer you a number of
  choices.  It is [4mstrongly[24m recommended that you go through them in
  order.

  The first question will ask if you wish to clear out your existing
  configurations for your capture cards.  Initially, you should say
  "YES" so that there are no surprises later.

  The next question will ask you if you wish to clear out your video
  source information.  You should answer "YES" to this as well.

  Once the graphical setup starts, you'll see that there are four
  choices.

  1. General

  2. Capture Cards

  3. Video Sources

  4. Input Connections

  Use the arrow keys to move around, and press the space bar to select
  which option you wish to configure.


  [1m9.1.1.  General[0m

  The first screen of the General configuration deals with IP addresses
  of the system that you're running setup on and any master backend you
  may have.  If you've only got one machine, then the default values are
  fine and you can move to the next page by pressing the space bar.  If
  you need to move around the screen, use the arrow keys to move focus
  between settings, not the mouse.

  If you will have multiple backends, then [4mdo[24m [4mnot[24m use the "127.0.0.1" IP
  address.

  It is very strongly discouraged that you make any changes to the port
  settings from the defaults.

  Once you're satisfied with the values, move the focus down to Next and
  hit the space bar.

  The next screen details the Host-specific Backend setup.  This is
  where you will set the specific directory paths for this particular
  backend.  Make sure that you've followed the steps at the beginning of
  this section and created a directory that exists and that MythTV will
  have write privileges to.  When you're done, press Next to continue,
  taking you to the Global Backend Setup.

  On the Global Backend Setup configure your backend with the
  appropriate settings.  Use the left and right arrow keys to iterate
  through the choices available on each setting, and the up and down
  keys to move between settings.  Move to Finish when you're done and
  press the space bar, taking you back to the main configuration screen.


  [1m9.1.2.  Capture Cards[0m

  You should have no capture cards defined, so the highlight will be on
  (New Capture Card).  Press space to begin.

  Choose the appropriate settings for your particular tuner.  Use the
  arrow keys to move around and to make your choices, and press RETURN
  when complete.  Pressing RETURN will take you back to the Capture
  Cards screen; if you have additional capture cards in this machine,
  press the space bar when the highlight is on the (New Capture Card)
  row to define another card.  Once you have no additional cards to
  setup, press ESC.


  [1m9.1.3.  Video Sources[0m

  When you start, the highlight should be on (New Video Source).  Press
  the space bar to begin.  The first field asks for the name of the
  video source.  You may choose something easy to remember, like
  "Antenna" or "Cable".  Once you've chosen a name, press the down arrow
  to move to the next field.  If you're in North America, move to the
  Zip/postal code field and put in the appropriate value.

  If you're outside of North America, then some manual interaction will
  be required with XMLTV.

  [1mNOTE[22m:  If you are in North America, and you enter your Zip/postal code
  and nothing seems to happen for a very very long time, it is possible
  that XMLTV is waiting for you to provide some input.  Use ALT-TAB or
  whatever key combination your window manager uses to switch programs
  and look for a terminal window running XMLTV that may be waiting for
  input.

  Once you have chosen your provider, press RETURN to continue.  XMLTV
  will now begin collecting the initial data for your location.  The
  screen may blank for a few seconds to several minutes, depending on
  the load of the listings provider and the speed of your connection to
  the Internet.  Be patient!

  You will then be returned to the Video Sources screen.  If you have
  multiple video sources available, such as Antenna, Cable, etc, go
  ahead and define them all, even if they're not all going to be
  physically connected to the master backend server.  Once you're done,
  press ESC to return to the main screen.


  [1m9.1.4.  Input Connections[0m

  The final configuration item is Input Connections.  On this screen,
  you will associate the various video sources you defined earlier with
  a physical input to a encoder card.  It's entirely possible that you
  have multiple tuners, and each tuner has a different input, so on this
  screen you let MythTV know which device will connect to which input
  source.


  When you start this screen, you should see a listing of the various
  input connections available on each of the Capture cards you defined
  earlier.  For example, you may have a capture card with a tuner, a
  SVideo and a Composite connection.  If you wanted to associate the
  tuner (a.k.a., "Television") with an "Antenna" source you defined in
  Video Sources, you would move to the /dev/videodevice (Television) ->
  line and press the space bar.  Using the left and right arrow keys
  will show you the various choices you have already created for video
  source.  In our case, you would use the left/right cursor keys until
  "Antenna" was shown in the Video Source field.  Press down to move to
  the next setting, all of which should be self-explanatory.

  Once you're done, press RETURN to go back to the Input Connections
  screen.  You would then finish associating the video sources to any
  other hardware devices you have available.

  [1mNOTE[22m:  Don't add a video source to a hardware input if you don't
  actually have anything connected there.  For example, adding "Cable"
  to the Tuner and to the Composite inputs without having something
  connected to Composite will lead to blank recordings.

  Press ESC to return to the main menu, and press ESC again if you have
  no further items to configure, thereby returning you to the command
  line.


  [1m9.2.  Post-configuration.[0m

  Run the mythfilldatabase program as directed.  The master backend will
  obtain guide data for all the video sources you defined during setup.

  Once mythfilldatabase has finished, start the master server before
  continuing.


       $ mythbackend



  mythbackend will print information about connections and what it's
  doing to the console.  If you'd like to see the options that are
  available for mythbackend, type mythbackend -h for help.

  As of 2003-10-03, the available options are:


       $ mythbackend -h
       Valid options are:
       -l or --logfile filename       Writes STDERR and STDOUT messages to filename
       -p or --pidfile filename       Write PID of mythbackend to filename
       -d or --daemon                 Runs mythbackend as a daemon
       -v or --verbose debug-level    Prints more information
                                      Accepts any combination (separated by comma)
                                      of all,none,quiet,record,playback,
                                      channel,osd,file,schedule,network
       --printexpire                  List of auto-expire programs
       --printsched                   Upcoming scheduled programs



  Running mythbackend as a daemon and using the logfile option will
  allow you to have mythbackend automatically start up during the boot
  process.  For example, you may add this to your rc.local file, or you
  can follow the steps outlined in the section called ``I'd like to
  automatically start mythbackend at system boot time''.


  [1m9.3.  Configuring a non-master backend.[0m

  Configuration of a non-master backend follows the same general
  procedure as that of the master backend, with the exception that you
  skip over the "Video Sources" step.  All possible video sources need
  to be defined on the master backend system; only the master backend
  will query a listings provider to obtain guide data for all the slave
  backends.

  Make sure that the IP addresses on the General setup screen are
  accurate.  If the slave backend can't communicate with the master
  backend due to IP address misconfiguration then MythTV will not
  function properly.

  Ensure that you've granted access to the master MySQL database for
  remote backends as discussed in the section titled ``Modifying access
  to the MySQL database for multiple systems'' and that you've edited
  the /usr/local/share/mythtv/mysql.txt file and put the correct IP
  address for the database server.

  [1mNOTE[22m: Do not run mythfilldatabase on a non-master backend.


  [1m9.4.  Configuring and running mythfilldatabase.[0m

  [1mNOTE[22m:  [1mmythfilldatabase [22mmight take a while to complete, depending on
  any number of factors, most of which you can't control.  It's best to
  just let the program run to completion.

  [1mmythfilldatabase --manual [22mis another option; the manual option will
  allow you to fine tune channel frequencies and specify which channels
  will be added to the database.  If you are not using the tv_grab_na
  grabber, you must use the [1m--manual [22moption.

  [1mmythfilldatabase --file [22mis an option if there isn't an XMLTV grabber
  for your country, but you [1mdo [22mhave an XML formatted listings file
  created by some other program.

  [1mmythfilldatabase --xawchannels [22mis an option if you have used [1mxawtv [22mto
  fine-tune your channels and would like to import the fine tuning
  offsets into MythTV.



  [1m9.4.1.  Setting mythfilldatabase  to run from cron[0m

  In order to keep your database filled, [1mmythfilldatabase [22mshould be run
  once a day.

  There are two ways to accomplish this:  either as a user-based cron
  job, or as a system based cron.  If you use a user-based cron, you can
  select the time that the cron job will be run.  A system-based cron
  job will run at the same time as any other system cron jobs.

  If you are a Mandrake 9.0 user and wish to use a system cron job, you
  can perform the following steps:


       $ cd configfiles
       $ su
       # cp mythfilldatabasecron /etc/cron.daily


  If you want to know what time your job will run, you can do the
  following:


       # cat /etc/crontab
       SHELL=/bin/bash
       PATH=/sbin:/bin:/usr/sbin:/usr/bin
       MAILTO=root
       HOME=/

       # run-parts
       01 * * * * root nice -n 19 run-parts /etc/cron.hourly
       02 4 * * * root nice -n 19 run-parts /etc/cron.daily
       22 4 * * 0 root nice -n 19 run-parts /etc/cron.weekly
       42 4 1 * * root nice -n 19 run-parts /etc/cron.monthly
       # exit
       $



  We can see from the display that the cron.daily job will run at 0402
  every morning.

  If you wish to specify a custom time, then the user-based cron job is
  the better method.

  The default [1mconfigfiles/mythcrontab [22mfile will run the [1mmythfilldatabase[0m
  program every day at 0430.  If you want to change this, then open the
  configfiles/mythcrontab file in your favorite editor and modify it as
  you like.  Once you're satisfied with the time that [1mmythfilldatabase[0m
  will run, save and exit, and return to the shell prompt.


       $ cd configfiles
       $ crontab mythcrontab
       $ crontab -l  NOTE: this is a lowercase L.
       # The following will run the mythfilldatabase shell script at 0430
       # every day.  Format is
       # minutes hour day_of_month month day_of_week
       # man 5 crontab for more information
       # Need to use a shell script because the QTDIR environment variable isn't
       # being honored by crontab?
       # The next text should be all on the same line.
       30 04 * * * /bin/bash $HOME/mythtv-0.11/configfiles/mythfilldatabasecron
       $



  As you can see, [1mmythfilldatabase [22mwill now be run at 0430 every day.

  If you decide to alter the time that the [1mmythfilldatabase [22mruns, you
  can use the crontab command to open your existing job and edit it in
  place.


       $ crontab -e



  The [1mcrontab -e [22mcommand will allow you to edit the existing crontab.
  [1mNOTE[22m:  By default, the crontab will use [1mvi [22mas your editor.  If you
  don't like to use [1mvi[22m, make sure that you've set VISUAL to something
  other than [1mvi[22m.
       $ export VISUAL=/usr/bin/joe
       $ crontab -e



  This will cause [1mcrontab [22mto use [1mjoe[22m, a visual editor that uses the
  Wordstar command sequence.  You may use [1memacs[22m, or any other editor
  that you're comfortable with.  You may also add the EXPORT command to
  your .bashrc or to the /etc/profile.d/mythtv.sh file.


  [1m10.  Configuring mythfrontend.[0m

  Once you have completed configuration of your backend systems, the
  next step is to configure the frontend client.  You should run the
  MythTV setup program before using any other modules such as MythMusic,
  etc. to correctly initialize the database.

  When you start mythfrontend, you should have a number of choices.
  Before doing anything, go to TV, then to Setup and configure the
  frontend client.


  [1m10.1.  General[0m

  The General screen has configuration items that don't really fit
  anywhere else.  The first few configuration items asks you to indicate
  the number of seconds to record before or after a program, which is
  useful if the broadcast network or your system clock are out of sync
  and will help prevent you missing the beginning or end of a program.

  To change the value, use the left and right arrow keys to increment
  and decrement the number of seconds.  When you're satisfied with the
  result, use the down arrow to put the input focus on the Next button
  or press RETURN to continue to the next page.

  The next page has a number of options to do with how channels are
  displayed on your system.  The help text will give you more
  information.  Move the focus to Next and press the space bar to
  continue.

  The final General page sets up some final configuration items.  See
  the help text for more information.


  [1m10.2.  Appearance[0m

  This set of screens is mostly concerned with how MythTV will look on
  your system.  From here, you can choose different themes and set the
  resolution of your system.


  [1m10.3.  Program Guide[0m

  Fairly self explanatory.  Note that the alternate program guide does
  not use the same font settings as defined in Appearance, so if the EPG
  is unreadable this is where you make the adjustments to fonts, number
  of elements displayed, etc.


  [1m10.4.  Playback[0m

  The one configuration item which may cause problems on your system is
  the "Deinterlace playback" setting.  MythTV uses a linear blend
  algorithm for deinterlacing, which will improve how the image looks on
  your screen.  Deinterlacing requires that your processor support SSE.
  (Streaming SIMD Extensions, aka "MMX2").  Early Intel Celeron (those
  that don't use the Coppermine 0.18um core and are usually <600Mhz),
  Pentium Pro and Pentium II CPUs do not have SSE, so make sure that you
  haven't enabled deinterlacing if your processor doesn't support it. If
  you enable it, and your processor doesn't support SSE, you will get
  "Illegal Instruction" errors.

  To determine if you've got SSE on an Intel processor, you can:


       $ cat /proc/cpuinfo
       [snip]
       flags           : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge mca
       cmov pat pse36 mmx fxsr sse



  Notice the [1msse [22mat the end of the line - this tells you that this
  processor will be able to deinterlace correctly.

  On an AMD processor, look for "3dnow" in the cpuinfo line; "3dnow" is
  AMD's implementation of SSE instructions, so if your processor has
  3dnow you shouldn't have any issues with deinterlacing.


  [1m10.5.  Recording[0m

  Currently, MythTV supports a number of different video encoders. There
  are two software options and two hardware options. The software
  options are MPEG-4 and RTJPEG. The hardware options are MPEG-2 and
  Hardware MJPEG. Take note that RTJPEG has lower CPU demands than
  MPEG-4, but makes large files, while MPEG-4 has higher CPU demands
  than RTJPEG, but makes smaller files.  Hardware MJPEG is only for use
  with MJPEG capture devices (Zoran-based cards; see
  http://mjpeg.sourceforge.net <http://mjpeg.sourceforge.net>). MPEG-2
  is the format used by the hardware-based PVR-x50 encoder. Note that
  MPEG-2 is not a selectable option in the Recording setup option, but
  this is what PVR-x50 cards will always use for initial video capture
  (which can later be transcoded), regardless of what codec you choose
  for Default and/or Live TV.

  [1mNOTE[22m: although the width and height can be changed to almost anything,
  if you start MythTV and don't see video or you get "segmentation
  fault" errors, it is likely that the video4linux (v4l) subsystem did
  not like the height and width parameters specified.  It's best to
  leave the default as-is until you're sure that MythTV is operational.


  [1m11.  Using MythTV.[0m

  The keys.txt file describes what the various keyboard commands are.

  [1mNOTE to Red Hat users[22m:Red Hat Linux 9/8.0 ships with Gnome as the
  default desktop environment.  However, Gnome seems to have issues with
  window focus and window switching which sometimes cause mythfrontend
  to obscure the video. KDE does not seem to have any such issues.
  Therefore you will need to switch to KDE by selecting
  RedHatMenu>Extras>System Settings>Desktop Switching Tool and choose
  "KDE".



  [1m11.1.  Using themes with MythTV.[0m

  MythTV is "themeable", meaning that the visual appearance of the
  program can be modified by the user without re-compiling or altering
  the program functionality.  The MythTV website has a Themes section;
  pick a theme you'd like to use and download it to your system.

  Once it's on your machine, you must move the file and untar it:


       $ su
       # cp funhouse.tar.gz /usr/local/share/mythtv/themes
       # cd /usr/local/share/mythtv/themes
       # tar -xjf funhouse.tar.gz
       # exit



  The theme will now be available in the mythfrontend Appearance
  section.


  [1m11.2.  Adding DirecTV information to the database.[0m

  A script for adding DirecTV information into the database has been
  written by tarek Lubani  <mailto:tarek@tarek.2y.net> and is available
  at http://tarek.2y.net/myth/ppv.pl <http://tarek.2y.net/myth/ppv.pl>.
  This is currently an external user-supplied program, so if you have
  issues with the script, please contact the author.


  [1m11.3.  Adding support for an external tuner.[0m

  MythTV supports changing the channel on an external tuner.  If you
  have an external tuner, such as a DirecTV or digital cable set top
  box, you should add /usr/local/bin/changechannel to your Input
  Connections in the mythbackend configuration GUI.

  The [1mchangechannel [22mprogram is not supplied with MythTV, so this is
  going to be dependent on what sort of external tuner you have.
  Example scripts for Sony and RCA receivers can be obtained from
  http://tarek.2y.net/myth/ <http://tarek.2y.net/myth/>.  This is
  currently an external user-supplied program, so if you have issues
  with the script, please contact the author.

  [1m12.  MythWeb.[0m

  The MythWeb allows you to use a web page to control various aspects of
  your MythTV system.  MythWeb is a separate application, but it's
  dependent on MythTV being installed and operational.


  [1m12.1.  Installation and prerequisites.[0m

  Download mythweb from http://www.mythtv.org/ <http://www.mythtv.org/>
  and save it to a location where you can find it.  The next step
  depends on whether your distribution has a web server and if you have
  PHP support.


  [1m12.1.1.  Mandrake 9.0[0m

  Mandrake 9.0 has [1mapache [22mand [1mPHP [22mpre-packaged, so installation is quite
  simple.  Once you have installed the two programs, either with the
  graphical installer (see instructions in ``Graphic Install Tools'') or
  through the command line (section ``Command Line''), and you've
  ensured that the [1mapache [22mserver will start at boot using the Mandrake
  Control Center.

  [1mNOTE[22m: Mandrake 9.1 users, perform the following:


       # urpmi apache apache2-mod_php php-mysql
       # chkconfig --level 345 httpd on
       # /etc/rc.d/init.d/httpd restart



  [1m12.2.  Completing the installation.[0m



       $ tar -xjf mythweb-0.11.tar.bz2
       $ cd mythweb-0.11
       $ su
       # mkdir /var/www/html/mythweb
       # cp -r . /var/www/html/mythweb
       # exit
       $



  Edit the /var/www/html/mythweb/config/conf.php file if required.

  By default, MythWeb uses an Apache .htaccess file to restrict access
  to the website and to configure some variables.

  To create the password file for Apache (if your system doesn't already
  have one), you could do something like this:


       # cd /var/www
       # htpasswd -c htpasswd mythtv
       New password:
       Re-type new password:
       Adding password for user mythtv



  See the man page for [1mhtpasswd [22mfor more examples.

  To access the web page, open a web browser and use [1mhttp://[name or ip[0m
  [1maddress]/mythweb/[0m

  [1mNOTE[22m: Make sure that you have a trailing slash on the URL, otherwise
  you will get a 404 Page not Found error.


  [1m13.  MythGallery.[0m

  MythGallery is a photo and slideshow application.  MythGallery is a
  separate application, but it's dependent on MythTV being installed and
  operational.

  [1m13.1.  Installation and prerequisites.[0m

  Download MythGallery from http://www.mythtv.org/
  <http://www.mythtv.org/> and save it to a location where you can find
  it.


       $ tar -xjf mythgallery-0.11.tar.bz2
       $ cd mythgallery-0.11
       $ qmake mythgallery.pro
       $ make
       # su
       # make install
       # exit
       $



  The configuration for MythGallery is accessed through the main Setup
  option in mythfrontend.  Make sure you set your pictures directory to
  wherever you're storing your photos.


  +o  Use the arrow keys to move around the thumbnails.

  +o  Use SPACE or ENTER to maximize a photo.

  +o  Use p or P to start the slideshow of all the files in the
     directory.  "Play" or "Pause" on your remote may also work.

  +o  Use SPACE or ENTER to advance to the next photo.

  +o  Use ESC to go up one level, or to exit out of the module if you're
     at the first level.

  +o  Use the [ and ] keys to rotate the image.

  +o  Use M to bring up the setup dialog.

  +o  Use I to import pictures; when a photo is maximized this will bring
     up photo information.

  +o  7 and 9 are used to Zoom Out and in, 2, 4, 6 and 8 are used to move
     around while in zoom mode, 5 centers and 0 exits zoom.


  [1m13.2.  Importing Pictures[0m

  The import path in the setup dialog is a colon separated list of
  directories and/or executable files.  When the import key is pressed,
  a new directory (the destination directory) under the current
  directory will be created and the import path will be searched.  If
  the item in the import path is a directory (the source directory), the
  contents of that directory will be copied to the destination
  directory. If you would like the source directory to be that of a
  removable device, it might be a good idea to use autofs.  See the
  automount howto at www.linuxdoc.org <www.linuxdoc.org> for info on how
  to get it working.

  If the item in the import path is an executable file, MythGallery will
  attempt to execute it with the destination directory as its sole
  argument.  Be careful when using executable scripts that the script
  runs unattended (doesn't need user intervention) and returns properly,
  otherwise it could create the appearance of MythGallery hanging (e.g.
  running [1msmbclient [22mand prompting for password).  Also be sure that
  scripts have executable permissions set.

  Here is an example script that a user may want to run on import:


       #!/bin/csh

       if ($#argv == 0) then
               echo "Usage: $0 dest_dir"
               exit
       endif

       cd $argv[1]

       # get stuff over the network
       wget http://www.somesite.dom/dir/file1.jpg
       wget http://www.somesite.dom/dir/file2.jpg
       wget http://www.somesite.dom/dir/file3.jpg

       # stuff that requires manual module loading and/or fs mounting
       modprobe camera_module
       mount /dev/camera /mnt/camera
       cp /mnt/camera/* $argv[1]
       umount /mnt/camera
       rmmod camera_module

       # perform some processing
       foreach pname (`ls *.jpg`)
               jpegtran -flip vertical $pname > $pname.new
               mv $pname.new $pname
       end



  [1m14.  MythGame.[0m

  [1m15.  MythMusic.[0m

  MythMusic has a number of prerequisites that must be satisfied before
  it is operational.  Depending on your distribution, some of these
  prerequisites can be satisfied through the various package managers.
  If your distribution doesn't offer pre-compiled versions of the
  software below, then follow the generic instructions for manually
  compiling and installing the software.

  The prerequisites for MythMusic are:

  +o  MAD

  +o  id3tag

  +o  libvorbis-devel

  +o  FLAC

  +o  libcdaudio


  +o  CDParanoia


  [1m15.1.  Manual installation of prerequisites.[0m

  These instructions are for distributions which don't have pre-compiled
  versions of the software necessary to run MythTV.

  Download MAD from http://www.mars.org/home/rob/proj/mpeg/
  <http://www.mars.org/home/rob/proj/mpeg/>  Save it to a directory you
  can find later.


       $ tar -xzf mad-0.14.2b.tar.gz

  [1m15.2.  Mandrake 9.0[0m

  Mandrake 9.0 has a number of the prerequisites available on the
  installation CD.  Some of the software you're going to need will have
  to be obtained from the "contrib" or "cooker" development
  repositories.  Applications downloaded from "cooker" come from the
  development branch, so there may be issues with some software.  It
  isn't recommended that you mix cooker and release-level software.


  [1murpmi [22mis the simplest tool for installation of packages from the
  command line.  The difficult part is the configuration, but this has
  been made easier at the following website:
  http://plf.zarb.org/~nanardon/urpmiweb.php
  <http://plf.zarb.org/~nanardon/urpmiweb.php> The website will allow
  you to choose a mirror site and then present the command-line
  configuration text for that mirror.  You will most likely need to add
  a "Contrib" mirror to your setup.  Once you have done that, you can
  proceed.  If [1murpmi [22mprompts you about other modules that need to be
  installed to satisfy dependencies, say "Yes".

       # urpmi libcdda0 libcdda0-devel libvorbis0 libvorbis0-devel
       # urpmi libcdaudio1-devel libid3tag0 libid3tag0-devel



  [1m15.2.1.  Additional options with MythMusic[0m

  Additional visualizations have been added to MythMusic.  If you wish
  to use these, there are some prerequisites you must install prior to
  compiling.


  +o  fftw

  +o  OpenGL

  +o  SDL

  fftw may be obtained from http://www.fftw.org/ <http://www.fftw.org/>.
  In Mandrake 9.1 it may be installed by typing:


       # urpmi libfftw2 libfftw2-devel



  OpenGL should be installed on practically all distributions.  However,
  you will need the devel module.  In Mandrake 9.1 it may be installed
  by typing:


       # urpmi libMesaGLU1-devel



  SDL may be obtained from http://www.libsdl.org
  <http://www.libsdl.org>.  In Mandrake 9.1 it may be installed by
  typing:


       # urpmi libSDL1.2 libSDL1.2-devel



  [1m15.3.  Red Hat Linux 9/8.0[0m

  Red Hat provides packages for several of the prerequisites, making
  installation very simple. Of the prerequisites, Red Hat provides
  packages for Vorbis, cdparanoia, SDL, and OpenGL (which you probably
  already have installed). To install these all at once, simply type
  (all on the same line):


       $ up2date --solvedeps libvorbis libvorbis-devel vorbis-tools cdparanoia-devel cdparanoia-libs cdparanoia SDL-devel SDL



  If you get the following message: "None of the packages you requested
  were found, or they are already updated" it probably means you already
  have all of those packages installed.

  You must install the remaining packages, (MAD, FLAC, libcdaudio and
  optionally fftw) manually following the installation directions above.
  When installing fftw do not use the rpm package offered on the website
  because it will cause an error, so use the source package instead.

  [1mNOTE[22m: you can use the instructions given at the ``automated
  installation section'' to install all of MythMusic in one step.


  [1m15.4.  Compiling MythMusic.[0m

  Once all the prerequisites have been installed, you can proceed with
  getting MythMusic going. Make sure that you run ./configure first.  If
  you wish to use the new visualizations, make sure you install the
  prerequisites.  Run ./configure --help for help.


  ______________________________________________________________________
  NOTE for Red Hat users: Before compiling, make the following modification
  to settings.pro, otherwise the compile will fail:

  Find the following text:
  INCLUDEPATH *= /usr/local/include

  immediately below that add
  INCLUDEPATH *= /usr/include/cdda

  save and close settings.pro and proceed with compiling MythMusic.
  ______________________________________________________________________



       $ qmake mythmusic.pro
       $ make
       $ su
       # make install
       # exit
       $ cd musicdb
       $ mysql -u root < metadata.sql



  [1m15.5.  Configuring MythMusic.[0m

  Configuration of MythMusic occurs in two places.  The main
  mythfrontend Setup is for global MythMusic configuration.  Go to the
  Setup/MythMusic/General Setup screen and adjust it for your particular
  setup.

  The second configuration screen is within the MythMusic program and
  will allow you rescan your music library, etc.

  Here's some explanation about the Ignore_ID3 and The
  NonID3FileNameFormat:

  If Ignore_ID3 is set to TRUE, MythMusic will try to determine the
  Genre, Artist, Album, Track Number, and Title from the filename of the
  mp3 file.  The NonID3FileNameFormat variable should be set to the
  directory/file format where the mp3 files are stored.  For instance, I
  store mine in the above shown Genre/Artist/Album/Track format.
  MythMusic will then use this information to fill in the proper fields
  when it populates the musicmetadata table rather than searching for an
  ID3 tag in the mp3 file.

  The files can be laid out in any format, such as:

  Genre/Artist/Album/Title Artist/Genre/Album/Title Artist/Album/Title
  (with Genre left as Unknown)
  The track number is optional but can be specified with the title by
  using the TRACK_TITLE keyword instead of TITLE.  If TRACK_TITLE is
  used, then the filename can have a space, hyphen, or underscore
  separating the track number from the track title.  Keywords are case
  insensitive, so if you specify GENRE it's the same as Genre in the
  format field.

  The Ignore_ID3 option does not disable the code that determines the
  track length, just the portion that tries to read ID3 info.


  [1m15.6.  Using MythMusic.[0m

  MythMusic is fairly simple to use.  It is recommended that you insert
  the CD before selecting "Import CD".  You should also ensure that your
  system doesn't try to automount the CD and begin playing it
  automatically.

  Another item to consider:  there are some CDs that contain computer
  data that runs as a "CD Extra" when inserted into some Windows PCs and
  Macintoshes.  As of 2003-06-10, MythMusic doesn't support track
  skipping or individual track selection, so if you have a CD with "CD
  Extra" data you will not be able to encode it; MythMusic will hang
  attempting to encode the non-audio data.

  Here's some information on playlist management:

  Q: How do I create a new playlist?  A: Using the MythMusic "Select
  Music" menu option, setup the playlist as you normally would by adding
  songs or other playlists as needed.  When you are ready to save the
  new playlist, highlight "Active Play Queue" at the bottom of the
  selection tree and hit the "i" key. This will pop up a menu allowing
  you to name and save the new playlist.  You can also hit Enter to
  bring up the popup on the Active Play Queue. This does not work on the
  playlists above, as Enter is obviously bound to checking/unchecking
  the boxes. Any number (ie. keypad on remote) will also bring up the
  menu in both cases.

  Q: How do I enter the playlist name in the text field without a
  keyboard?  A: Use the keypad number keys (bound to your remote) to
  select letters quasi-cell phone style. Keys 2-9 work pretty much like
  any cell phone text entry. 1 cycles through a few special characters,
  delete, and space. 0 is like a CAPS LOCK. Hard to describe, fairly
  easy to use. You will soon be able to specify the cycle timing in a
  Setup screen. You can type fairly quickly through a combination of
  jumping around the number keys AND hitting a non-number key (right
  arrow is particularly good for this) to force the current character.

  Q: How do I edit a playlist?  A: Highlight the playlist in the
  selection tree and hit the "i" key then select "Move to Active Play
  Queue" in the popup.  You can now modify the "Active Play Queue" like
  normal, adding songs and playlists by selecting them from the song
  tree.  When you are done, highlight the "Active Play Queue" in the
  selection tree and hit the "i" key then select "Save Back to Playlist
  Tree".  And whatever you were editing as your Active Queue before you
  moved an existing playlist "on top" of Active reappears. Think of
  Active has having a push on, pop off capability, but with a depth of
  only 1.

  Q: How do I delete an item from a playlist?  A: Highlight the item in
  the selection tree and hit the "d" key.

  Q: How do I rearrange the songs in my playlist?  A: Highlight a song
  and hit the "space" bar, the song will now have pair of red arrows in
  front of it.  Use the up and down arrow keys to move it around in the
  playlist.  When you have it where you want it, hit the "space" bar
  again.

  Q: How do I delete a playlist?  A: Highlight the playlist in the
  selection tree and hit the "i" key then select "Delete this Playlist"
  from the popup.


  [1m15.7.  Troubleshooting MythMusic.[0m

  You may run into errors when running MythMusic.

  [1m15.7.1.  When I run MythMusic and try and look up a CD, I get an error[0m
  [1mmessage[0m

  The full text of the message will say:

  databasebox.o: Couldn't find your CD. It may not be in the freedb
  database.  More likely, however, is that you need to delete  /.cddb
  and  /.cdserverrc and restart mythmusic. Have a nice day.

  If you get this message, you should go to the home directory of
  whatever user MythMusic is running as and type:


       rm .cdserverrc
       rm -rf .cddb/



  These files aren't automatically deleted because of a conscious design
  decision by the author that programs that automatically delete things
  are bad.

  The files are used to locally cache CD lookups. If you are re-
  inserting CDs, your machine will not actually have to go out to the
  Internet to determine what is on them.  However, the URL used to
  access the freedb database has recently changed, so the stale
  information in the files from previous runs of MythMusic would cause
  the error above.  Once the files have been deleted the stale
  information will be gone and your local database will be rebuilt as
  you use CDs.


  [1m16.  MythWeather.[0m

  The MythWeather module will obtain the weather information for the
  location that you specify.  You must be running MythTV v0.10 or later
  in order to use MythWeather.


  ______________________________________________________________________
  NOTE for Red Hat Linux 8.0 users: Red Hat 8 users must make the following
  modification, or several weather icons will fail to be installed.

  From the mythweather build directory move to the mythweather sub-directory
  and edit the Makefile there.

  Find and comment out (using a '#' symbol) the following line:

  strip "$(INSTALL_ROOT)/usr/local/share/mythtv/mythweather/images/"
  ______________________________________________________________________



  Change into the MythWeather directory, then make and make install:


       $ cd mythweather
       $ qmake mythweather.pro
       $ make
       $ su
       # make install
       # exit



  MythWeather uses MSNBC.com as its source for weather data and
  weather.com for its radar image.

  These are the keyboard commands for MythWeather:


       Left Key             Goes back one page, and extends the time spent
                            on the page you are on.
       Right Key            Goes forward one page, see above.
       Space                Pause, wait on the current page until space is hit
                            again.
       Numeric Keys         You can check other weather by keying in other ZIP codes.
       Enter Key            Switch between Celsius and Fahrenheit. Can also
                            be used a way to force a data update.
       "m" Key              Resets the location to the database default, then updates the data.
       "i"                  Enter / Save settings
       ESC                  Exit the settings screen without saving / Exit the program



  MythWeather also has an "Aggressiveness" setting.  This affects how
  long MythWeather waits for data from the msnbc.com website before
  timing out.  If you are on a slow connection, or have a slow DNS, or
  MythWeather just doesn't seem to be working and you've already tried
  everything else, then try increasing the aggressiveness level
  parameter.  This parameter is inverse; a higher number actually means
  that MythWeather will be less aggressive, and will therefore wait
  longer before timing out.

  MythWeather will print debugging information on the terminal.  If you
  wish to see additional debugging information while MythWeather is
  running, run mythweather from the command line with as mythweather
  --debug

  You may also force mythweather to re-run the configuration by starting
  it on the command line as mythweather --configure.  These two options
  are mutually exclusive.


  [1m17.  MythVideo.[0m

  The MythVideo application will allow you to use an external program to
  watch media files that are not directly supported by MythTV.

  Change into the MythVideo directory, then make and make install:



  $ cd mythvideo
  $ qmake mythvideo.pro
  $ make
  $ su
  # make install
  # exit



  The next step is to create the create the videometadata table in the
  database.  Simply do the following:


       $ cd videodb
       $ mysql -u mythtv -p < metadata.sql



  See MythVideo's README file for additional information.


  [1m18.  MythDVD.[0m

  MythDVD is an application which rips DVDs and makes them available for
  use with MythVideo.  You may also transcode the DVD content from
  MPEG-2 to other formats which should greatly reduce the amount of
  space the DVD material takes up on your hard drive.

  MythDVD has a number of prerequisites to enable transcoding
  functionality.  If you only wish to play DVDs rather than convert them
  to something like MPEG-4 or xvid you may skip the prerequisite
  installation step.


  [1m18.1.  Manual Compilation of Prerequisites.[0m


  [1m18.2.  Pre-compiled binaries.[0m

  Mandrake users may install the prerequisites this way:


       # urpmi libdvdread3 libdvdread3-devel a52dec liba52dec-devel
       # urpmi mplayer ogle xine



  Assuming that you've added a PLF mirror, you may also load the rest of
  the prerequsites using the following command:


       # urpmi xvid xvid-devel fame libfame0.9-devel transcode libdvdcss



  Next comes the configuration and compilation.  If you don't want to
  transcode, then the first command in the next example can simply be
  ./configure



  $ ./configure --enable-transcode
  $ qmake mythdvd.pro
  $ make
  $ su
  # make install



  Once that's done, ensure that you've added the appropriate table
  structures to the database:


       $ cd dvddb
       $ mysql -u root < metadata.sql

  This error can happen for the following reasons:

  +o  You have an AMD K6-2 or VIA C3 processor.  If you have either of
     these, make sure that you you followed the instructions in this
     ``section''.

  +o  You have an early production Intel Celeron, Pentium Pro or Pentium
     II.  If you have any of these processors, make sure that your
     ``deinterlace'' variable is set correctly.  Your CPU needs to
     support SSE instructions for deinterlace support.  You may check
     this by doing a $ cat /proc/cpuinfo and looking for "sse" in the
     processor flags section.

  [1m20.2.  mythfilldatabase failing.[0m

  If mythfilldatabase suddenly appears to be failing, check to see what
  version of XMLTV you're running.  Versions prior to 0.5.4 need to have
  the following change made: edit the
  /usr/lib/perl5/site_perl/5.8.0/XMLTV/ZapListings.pm file and perform a
  global search and replace, searching for "tvlistings2" and replacing
  it with "tvlistings".  [1mNOTE[22m:  It is highly recommended to run the
  latest version of XMLTV available.  In North America, zap2it, the
  listings provider, has been making numerous changes to their website
  which negatively impact XMLTV.

  [1m20.3.  MythTV seems to disappear; can't see video.[0m

  If you're using Gnome as your window manager, try switching to KDE.
  For Red Hat Linux 8.0 users, edit /etc/sysconfig/desktop and change
  "GNOME" to "KDE".

  [1m20.4.  Fast CPU, choppy or jittery video.[0m

  First, you should check that your kernel has been enabled for DMA:



  [mythtv@pvr mythtv]$ dmesg |grep DMA
      ide0: BM-DMA at 0xd800-0xd807, BIOS settings: hda:DMA, hdb:DMA
      ide1: BM-DMA at 0xd808-0xd80f, BIOS settings: hdc:DMA, hdd:pio
  hda: 156301488 sectors (80026 MB) w/2048KiB Cache, CHS=9729/255/63, UDMA(33)
  hdb: 80043264 sectors (40982 MB) w/2048KiB Cache, CHS=4982/255/63, UDMA(33)



  From the listing above, you can see that hda, hdb and hdc are set for
  DMA, and hdd is set for pio.  If your kernel is not reporting DMA
  being enabled, you may need to recompile your kernel. Check your
  motherboard's chipset (look in the "ATA/IDE/MFM/RLL support" section
  in "make menuconfig") for more information.

  Next, check that the hard drive has DMA enabled.  Use the [1mhdparm[0m
  program to check and enable DMA.


       # hdparm -d /dev/hd?



  will tell you the DMA status for your hard drives.  If you run [1mhdparm[0m
  with the -d1 parameter, it will turn DMA on.


  You may also setup your PC to do this at boot time, either by adding
  the command to your /etc/rc.local file, or by adding files to
  /etc/sysconfig.

  On Mandrake and other distributions, if you install [1mhdparm [22mfrom an RPM
  you will most likely get a /etc/sysconfig/harddisks file installed.
  This file will be parsed by the /etc/rc.sysinit script.  If you use
  the default harddisks file, your changes will affect all IDE devices
  (including CD ROMs).  If you wish to use different parameters for
  various devices, rename and/or copy the file to harddiskhda,
  harddiskhdb, etc.  Edit the file to your liking and on the next reboot
  your setting will be preserved.


  [1m20.5.  I keep losing all of my settings every time I compile![0m

  MythTV will overwrite any settings in /usr/local/share/mythtv.  If you
  want to make sure that you don't lose your modifications, make a
  directory ~/.mythtv and copy your mysql.txt file to this location.

  [1m20.6.  Compile errors.[0m

  Some compile errors are worse than others.  If you get an error that
  doesn't abort the compilation, and says something like:


       cc1plus: warning: changing search order for system directory
       "/usr/local/include"
       cc1plus: warning:   as it has already been specified as a non-system
       directory



  then it shouldn't be a problem.

  If you get an error like /usr/bin/ld: cannot find -lXext, the compiler
  is telling you that you don't have XFree86-devel installed, or that
  your distribution hasn't set it up ``correctly''.  This needs to be
  fixed before MythTV will compile.


  [1m20.7.  My screen goes blank, but comes back when I wiggle the mouse or[0m
  [1muse the keyboard.[0m

  This is due to DPMS, the Display Power Management System, which is
  used to save power by turning off your monitor when the system decides
  that it's not being used or to a screensaver that has defaulted to a
  blank screen.  Since it's likely that watching TV will not generate
  keyboard or mouse events for a time, you need to turn off DPMS and the
  screensaver.  There are a few ways to do this.  You may also need to
  check your BIOS for power saving modes and disable screen blanking
  there as well.

  Edit your /etc/X11/XF86Config-4 file, and look for:


       Section "ServerFlags"
           #DontZap # disable <Crtl><Alt><BS> (server abort)
           #DontZoom # disable <Crtl><Alt><KP_+>/<KP_-> (resolution switching)
           AllowMouseOpenFail # allows the server to start up even if the mouse doesn't work
       EndSection



  Add Option "NoPM" "true" and Option "BlankTime" "0"to the ServerFlags
  section.

  Also, look for:


       Section "Device"
           Identifier "device1"
           VendorName "nVidia Corporation"
           BoardName "NVIDIA GeForce 256 (generic)"
           Driver "nv"
           Option "DPMS"
       EndSection



  In this case, you would need to either delete the Option "DPMS" line,
  or change it to # Option "DPMS" to comment it out.  The next time you
  start XFree this change will take effect.

  Finally, check:



  Section "Monitor"
      Identifier "monitor1"
      VendorName "Plug'n Play"
      HorizSync 30-85
      VertRefresh 50-160

      # Sony Vaio C1(X,XS,VE,VN)?
      # 1024x480 @ 85.6 Hz, 48 kHz hsync
      ModeLine "1024x480"    65.00 1024 1032 1176 1344   480  488  494  563 -hsync -vsync

      # TV fullscreen mode or DVD fullscreen output.
      # 768x576 @ 79 Hz, 50 kHz hsync
      ModeLine "768x576"     50.00  768  832  846 1000   576  590  595  630

      # 768x576 @ 100 Hz, 61.6 kHz hsync
      ModeLine "768x576"     63.07  768  800  960 1024   576  578  590  616
  EndSection



  Ensure that there isn't an Option "DPMS" in the Monitor configuration.

  You can also turn off DPMS from the Command Line, but this will not
  survive a reboot.


       $ xset -dpms



  Using xset +dpms will turn it back on.

  Another technique to try, which will turn off the screensaver:


       $ xset s off



  You may also combine the command to turn off DPMS and the screensaver:


       $ xset -dpms s off



  Finally, depending on your distribution, you may be able to turn it
  off from within the control panel.


  [1m20.8.  I get segfaults / MythTV isn't doing anything.[0m

  [1m20.9.  Debugging with GDB.[0m

  Without details, the developers will not be able to determine if you
  have discovered a genuine code-bug,  or if the problem is with your
  system.  In order to determine what's going on, you must recompile
  MythTV with debugging support and run MythTV within [1mgdb[22m, the GNU
  debugger.

  Edit the settings.pro file.  Make sure that the top of the file looks
  like this:
       $ cat settings.pro
       CONFIG += debug
       #CONFIG += release



  Now, you need to clear out the old versions of the software to ensure
  that you're running with the debugging code, then compile and install.


       $ make clean distclean
       $ ./configure
       $ make
       $ su
       # make install
       # exit



  At this point, you now have debug-enabled software ready.  Let's
  assume that the problem you're having is in the setup program.


       $ cd setup

  displayed on the X console (usually ALT-F6 or ALT-F7) and still give
  you output and control of [1mmythfrontend[22m, either from the [1mssh [22msession,
  or by switching back to the text console by pressing CTRL-ALT-F1.  You
  can now continue troubleshooting using [1mgdb [22mas detailed in the

  [1m20.11.  Troubleshooting audio.[0m

  By Bruce Markey, mailto:bjm@lvcm.com <mailto:bjm@lvcm.com> [1mNOTE[22m:  the
  following instructions do not apply to PVR-250/350 encoders; the
  MPEG-2 file will have the audio embedded in the stream so it is not
  accessible using /dev/dsp.  See ``this'' in the PVR-250 ``section''
  for more information.

  Audio appears to be one of the bigger issues that users run into on
  the mailing list.  If the audio isn't configured correctly, then
  MythTV will often appear to hang, when in fact it is trying to
  manipulate the audio subsystem and failing.  You may or may not
  receive error messages indicating that the source of the error is the
  audio subsystem.

  You can not use [1mxawtv [22mto determine if your audio is working correctly,
  since [1mxawtv [22mis simply using the the analog sound patched through line-
  in to line-out. It doesn't need to digitize the sound unless you are
  using the recording function.

  A better test to verify that sound will work for MythTV (and recording
  with [1mxawtv [22mfor that matter) is to startup [1mxawtv[22m, mute the line-in then
  run aplay /dev/dsp. You should hear the recorded audio slightly
  delayed behind the realtime video.  Once this test succeeds, MythTV
  should work correctly because it writes to and read from /dev/dsp in
  the same way that [1maplay [22mdoes.

  To record audio along with video the audio signal must be digitized by
  a DSP so that the audio data can be stored in a file. On playback, the
  audio data is written to /dev/dsp and converted back to an analog
  signal. This analog signal should then be sent to your speakers. Here
  is what is needed in alsamixer:

  CAPTUR source - the analog source to be sent to the DSP. This should
  be set to the input source from the tuner card to the sound card. In
  most cases this is Line but this could also be Aux, CD, Mic, etc.,
  depending on how you connect the input cable. This source should be
  muted to prevent patching through the analog sound. The volume of this
  source will not affect the record level.

  Capture mixer - this sets the level for the analog to digital
  recording.  While a volume of 100% is recommended for testing,
  distortion may occur.  Lowering this level to 75% to 85% may result in
  better audio quality.  "Capture" should be marked as the CAPTUR
  destination.

  PCM mixer - this sets the level for the digital to analog playback.
  While a volume of 100% is recommended for testing, distortion may
  occur. Lowering this level to 75% to 85% may result in better audio
  quality.

  Master mixer - sets the level for the analog signal sent to line-out
  or the speakers.

  You may also want to ensure that /dev/dsp hasn't already been grabbed
  by another process, like [1mesd [22mor [1martsd[22m.  If /dev/dsp isn't available,
  then MythTV won't work.  Check your window manager documentation for
  instructions on disabling the sound manager.  If you wish to see what
  application is grabbing a resource, you can use the fuser command:


       # fuser -v /dev/dsp



  To disable aRts in KDE, go to KDE->Control Center->Sound->Sound System
  and uncheck the "Start aRts soundserver on KDE startup" box.  Run #
  killall artsd from the command line to stop the artsd program.

  If you're using multiple sound cards and multiple tuners, use
  alsamixer -c 1 to work with the second sound card.  The first card is
  #0, the second card is #1, etc.

  instructions which tell you how to modify the Themes makefile.
  ``Link''.


  [1m20.13.  The mythbackend program told me to look at this section.[0m

  mythbackend does a check to see if your sound device is capable of
  full duplex operation.  If it's not, it's most likely that you're
  going to run into issues when you try to record and play sound at the
  same time.  If your backend is a separate machine than your frontend,
  then there's no problem, since you're only going to be doing one thing
  at a time with the card.  Likewise, if you're running the frontend and
  backend on the same machine, but you're using btaudio or a Hauppauge
  PVR-250 as your recording source, and using the playback function of
  your soundcard, then you also shouldn't have an issue, since the sound
  card isn't being asked to perform two functions at once.

  If you can't get your soundcard to go full duplex and need it to, then
  check your distribution for updated sound drivers.  If your soundcard
  is not capable of full-duplex operation, either because the drivers
  don't support it, or it has been designed that way, then you're pretty
  much out of luck and will either need to purchase a new sound card, or
  will need to get btaudio ``operational''.


  [1m20.14.  My remote doesn't work / works sometimes and not others /[0m
  [1m"ghost" keypresses.[0m

  This can be due to a number of factors.  The simplest case is the
  "ghost" keypresses.  For me, it was due to compact fluorescent lights
  in the same room as the IR receiver, which the receiver was picking up
  as keypresses.  Once the lights were switched to incandescent bulbs,
  the ghost went away.

  You may have an issue with [1mlirc [22mmisinterpreting IR commands from a
  different remote.  I also have an issue where the Tivo "Peanut" remote

  If your remote has been properly configured, and [1mirw [22mand [1mirxevent [22mare

  There is no such thing as "Canada Cable"; Canada uses the same

  people used when they would discover that their channels were off-by-
  one, ie, when tuning to channel 42, they might get channel 41 or 43.
  This is actually due to the tuner on the video capture device being
  mis-detected.  You must manually specify the tuner type in your
  /etc/modules.conf.  See the video4linux mailing list
  (https://listman.redhat.com/mailman/listinfo/video4linux-list

  properly in other media players.

  At this point, you can read the MPlayer documentation and start the
  compile process.


  [1m21.2.  I'd like to use some other window manager.[0m

  MythTV is not dependent on any particular window manager.  If you wish
  to run a lightweight window manager, the configfiles/ directory has an
  example of a .twmrc and .fvwmrc file you may use.



  [1m21.3.  What capture resolution should I use?  How does video work?[0m

  While MythTV allows you to set various GUI and capture resolutions,
  not all combinations make sense.

  First, analog video signals have a defined vertical resolution.  In
  NTSC, the video standard specifies that there are 525 vertical scan
  lines.  Once the "extra" lines are removed (they're used to
  synchronize the video signal, and encode closed captioning data), you
  have 480 vertical lines.

  In PAL, there are 625 "raw" lines of resolution, with a net of 576
  vertical lines.

  Horizontally, the maximum you can expect from a Bt8X8 chip is 720.

  With this in mind, there are certain commonly accepted values for
  resolution.  While other values may be accepted, they will cause scan
  lines to be repeated or dropped.

  From "best" to "worst", in NTSC:

  +o  720x480 (but more commonly, 704x480.  "DVD" resolution)

  +o  640x480 4:3

  +o  544x480 (TiVo high resolution)

  +o  480x480 (Video CD resolution)

  +o  352x480 (ReplayTV "Standard" quality)

  +o  320x480

  +o  544x240

  +o  480x240

  +o  352x240

  +o  320x240

  As you can see, the lower quality values are half of the better ones.
  720x240 is possible, but isn't a good tradeoff relative to the number
  of vertical lines lost.  In a PAL country, the you would use values
  like 720x576 or x288.

  The higher resolutions will be more CPU intensive if you're using
  software encoding (PVR-250/350 will have minimal host CPU impact even
  if you're using 720x480). If the CPU is overtaxed, frames will be
  dropped causing uneven motion. You will likely see the best results at
  resolutions which average at least 10% CPU idle time.  You can use
  system tools such as top or sar to check the CPU % idle while
  recording.  If the CPU average usage is consistently exceeding 90%,
  frames will need to be dropped during peak times when more than 100%
  of the available CPU would be needed to process all of the frames.

  [1m21.4.  MythTV GUI and X Display Sizes.[0m

  MythTV is designed to be run as dedicated full screen TV application
  but can also be run as a desktop application on a computer monitor.
  Here are a few consideration for configuring sizes to best suit you
  needs.

  There are three sizes that are important for matching the MythTV GUI
  and full screen TV playback to fit the screen:


  +o  the X display size

  +o  the X Desktop (virtual) dimensions

  +o  the MythTV GUI dimensions

  The MythTV GUI uses its GUI dimensions regardless of the other two and
  is anchored to the upper left corner of the X Desktop.

  The MythTV full screen mode uses the X display size dimensions
  regardless of the other two and is anchored to the upper left corner
  of the X display.


  [1m21.4.1.  X Dimensions[0m

  For output to a Television, common resolutions are 640x480, 800x600,
  and some rare devices support 1024x768. Generally, higher resolutions
  are better. However, you may find that you prefer the picture quality
  at one of the lower resolutions. Everything in MythTV is scalable and
  should 'fit' regardless of the resolution you choose.


  Edit your X configuration file, usually "XF86Config-4", so that the
  the resolution you want to use is listed first in the lists under
  "Screen". If this resolution is higher than the resolutions supported
  by your output device, you will see a 'panning' effect where moving
  the mouse to the edge will scroll around a desktop area which is
  larger than the display size. If this happens, edit your X
  configuration file to match the display size then restart X.


  [1m21.4.2.  MythTV Dimensions[0m

  In 0.10 and later, from "mythfrontend" go to Setup->Appearance.  The
  default for the height and width is "0" - this will cause MythTV to
  automatically size itself to full screen. To ensure that your new
  dimension settings take effect, exit and restart MythTV.

  [1mNOTE[22m: When the GUI is full screen, you may need to set your window
  manager to 'Click to Focus' for windows to stack properly.

  The fonts for the GUI and OSD will scale to whatever sizes you use.
  Most font sizes can be changed in setup selections. Make sure to use
  fonts large enough to be read on a TV screen from a distance.

  The full screen TV size is based on the X display size. For Xinerama,
  you can specify a screen in Setup->General. The picture will be
  stretched to fit the entire screen regardless of the ``capture
  resolutions'' used.


  [1m21.4.3.  Overscan Dimensions[0m

  Because picture edges can be ragged and screen edges aren't straight,
  Television is designed to project an image larger than the physical
  screen.  This is called "overscan". Underscan is fitting the entire
  image inside the screen. This is useful for computer monitors so that
  toolbars and scrollbars at the edges can be seen.

  For best results, match the X display area as close as possible to the
  edges of the physical screen. This can only be adjusted by your tv-out
  device or by the settings for the television set. Many sets have these
  adjustments in a 'service mode'.

  MythTV has settings for "Overscan" in Setup->Playback. These can not,
  and do not, cause the image to display beyond the edge of the X
  display area. The purpose of these settings are to cut off rough edges
  and to expand the image so that objects will appear to be the same
  size as a normal overscanned TV picture.


  [1m21.4.4.  MythTV on the Desktop[0m

  When using MythTV on a high resolution desktop monitor, set the MythTV
  GUI dimensions to something much smaller than your X display
  resolution but still large enough to read the fonts. The GUI screens
  will always be in the upper left hand corner. However, your window
  manager may be able to minimize these (ALT-F4 in KDE for example).

  The TV picture will start in full screen mode. Press "f" to put the
  picture in a window that can be moved and resized. By default, the
  picture uses the recording resolution for its dimensions. If you check
  the box "Fixed Aspect Ratio" in Setup->Playback, the windowed picture
  will always be resized to normal 4:3 shape.

  [1m21.7.  btaudio[0m

  btaudio allows you to obtain the audio data from your tuner card
  directly over the PCI bus without using a soundcard.  This is useful
  if you would like to use multiple tuner cards in a system without
  adding a soundcard for each one, or if your existing soundcard is not
  capable of full-duplex operation.

  In order to use btaudio, your tuner card will need certain hardware
  installed on it, and that hardware must be wired correctly.  The chip
  that will allow you to use the btaudio module is the MSP34xx.
  However, having a MSP34xx is no guarantee that you will be able to use
  the btaudio module.

  As of 2003-03-31, this is the current list of cards and their status:
  Works with btaudio:


  +o  Hauppauge WinTV-radio with dbx-TV stereo, model 401

  +o  Hauppauge WinTV-Theater, model 495, 498 (Europe)

  +o  ATI TV Wonder


  The following cards do not work:

  +o  Pinnacle Studio PCTV Pro - note: this has a MSP34xx, but it's not
     wired correctly to the BT878 chip.

  +o  ATI TV Wonder VE

  +o  Leadtek Winfast 2000 XP (PAL, UK and NTSC)

  +o  I/O Magic PC-PVR.  No MSP34xx chip.

  The following cards have been reported to work, but have issues:

  +o  Avermedia AVerTV Studio (no digital DSP output, "whiney noise" on
     analog)

  See contrib/example.modules.conf.for.btaudio for an example file on
  how to configure btaudio on your system.

  Once btaudio loads, it should register additional /dev/dsp and
  /dev/mixer devices.  Typing $ dmesg will let you know what's going on.


  [1m21.8.  Removing unwanted channels.[0m

  If [1mmythfilldatabase [22mgrabbed a channel which you do not want to include
  in your TV listings, you can remove the entries from the xmltv config
  file and the mysql database.  This often happens with premium
  channels; for example, HBO or Showtime may be available on your cable
  TV system, but is scrambled because you're not a subscriber to that
  channel.  Since you can never watch it, you want to get rid of it.

  First, comment out the channel from the  /.mythtv/<sourcename>.xmltv
  file by inserting a "#" in front of the unwanted entry. This will
  prevent [1mmythfilldatabase [22mfrom grabbing future listings.

  Next, delete the unwanted item from the channel table so that it will
  not appear in the EPG or when changing channels.  The channels will
  always have "1000" added to them, so for example, assuming that HBO is
  channel 15:


       $ mysql -u root mythconverg
       mysql> delete from channel where chanid = '1015';



  Old program data will be removed over the course of a week. However,
  you may want to immediately delete any current program listings for
  the channel that has been removed:


       $ mysql -u root mythconverg
       mysql> delete from program where chanid = '1015';



  [1m21.9.  I'd like to use NFS.[0m

  You may want to use a central server to store your files.

  On the host machine, (in this case, the hostname is "masterbackend")
  you'll want to edit your /etc/exports file and use something like:
       /var/video (rw)



  To export the /var/video directory with read / write privileges.

  On the "slave" machine, you'll want to edit the /etc/fstab file and
  add something like:


       masterbackend:/var/video /var/video nfs rsize=8192,wsize=8192,soft,nfsvers=3



  Then run # fstab -a to re-read the file to mount the file system.

  In this case, the source is a machine called "masterbackend" which is
  exporting the directory "/var/video", which we're mounting locally at
  "/var/video".  The rsize and wsize options are used to increase the
  performance of NFS; soft mean that NFS will eventually timeout on an
  error, and the nfsvers is required for filesizes over 2GB.

  Here's a method for automatically starting mythbackend submitted by
  Mike Thomson (mailto:linux@m-thomson.net <mailto:linux@m-thomson.net>)
  and Stu Tomlinson (mailto:stu@nosnilmot.com
  <mailto:stu@nosnilmot.com>).

  Copy the files from the MythTV contrib directory or from Mike's web
  site (http://m-thomson.net/mythtv/ <http://m-thomson.net/mythtv/>) as
  follows:

  etc.rc.d.init.mythbackend should be made executable and copied to
  /etc/rc.d/init.d/:


       $ cd contrib
       $ su
       # chmod a+x etc.rc.d.init.d.mythbackend
       # cp etc.rc.d.init.d.mythbackend /etc/rc.d/init.d/mythbackend



  etc.sysconfig.mythbackend should be copied to /etc/sysconfig/:


       $ cd contrib
       $ su
       # cp etc.sysconfig.mythbackend /etc/sysconfig/mythbackend



  Edit /etc/sysconfig/mythbackend if you want to change the defaults
  (the userid that should start mythbackend, location of the logfile and
  (if required) the name and location of the mythbackend binary).

  Use [1mchkconfig [22mto make sure the script is called when entering
  runlevels 3, 4 or 5:


       $ su
       # chkconfig --level 345 mythbackend on
       # exit
       $



  [1m21.11.1.1.  Log files[0m

  By default, the log file for mythbackend will be written to
  /var/tmp/mythbackend.log. This has been tested and is known to work on
  Mandrake and Red Hat, but many people prefer to place logs under
  /var/log/.

  To do this, create a group called mythtv (or anything you prefer) and
  add your usual MythTV users to that group. If you changed the user
  that starts mythbackend from the default of root you [4mmust[24m perform this
  step.

  Create the directory /var/log/mythtv and set its permissions as
  follows:
       $ su
       # mkdir /var/log/mythtv
       # chown root:mythtv /var/log/mythtv
       # chmod 0775 /var/log/mythtv
       # exit
       $ ls -ld /var/log/mythtv
       drwxrwxr-x    2 root     mythtv       4096 Apr 28 21:58 /var/log/mythtv/
       $



  [1m21.11.1.2.  Mandrake 9.x[0m

  Mandrake adds one more twist in the form of the msec utility, which
  runs regularly and (at the default or any higher security level) sets
  permissions on many files, including those under /var/log.

  To tell msec about the MythTV log files and their directory, you need
  to edit the /etc/security/msec/perm.local file to include the
  following:


       # /etc/security/msec/perm.local
       # Local overrides to the msec program
       #
       # Full file path                user.group              permissions
       /var/log/mythtv/                root.mythtv             775
       /var/log/mythtv/*               root.mythtv             664



  A copy of the above has been included in the contrib/ directory.  You
  may add it by typing:


       $ cd contrib
       $ su
       # cat etc.security.msec.perm.local >> /etc/security/msec/perm.local
       # exit



  Finally run the msec tool to check and implement your changes.


       $ su
       # msec
       # exit
       $



  [1mNOTE[22m: msec can only [4mreduce[24m the permissions of files, so if you don't
  get the results you expect, check that you're not asking msec to add
  missing permissions to the files or directories you created.

  [1m21.11.2.  Gentoo[0m

  [1m21.12.  Advanced Backend Configurations.[0m

  MythTV is flexible in the way that you define multiple backend tuner
  configurations.  The only hard-and-fast rule is that the Master
  Backend [4mmust[24m have a capture device defined, but shouldn't imply that
  the capture device in the MBE must be the first capture card defined
  in the database.

  One example of an advanced configuration is the round-robin scheme.
  Rather than defining all of the cards on the master, you could first
  go into setup on the master to define globals such as the general
  configuration and the channel lineup but not the host-specific
  configuration item like the capture card.  In this example, we will
  use a 4 tuner configuration, where two slaves have one card each and
  the master has two.

  1. Add the first capture card on one of the slaves.  Complete the
     configuration, connecting the input source to the card.  This will
     get cardid #1 in the database.  Exit setup.

  2. Configure the first capture card on the master backend.  This will
     get cardid #2 in the database.  Exit setup.

  3. Configure the first capture card on the second slave.  This will be
     cardid #3 in the database.  Exit setup.

  4. Configure the second capture card on the master backend.  This will
     get cardid #4 in the database.  Exit setup.

  Using this scheme, the master backend will not use both capture cards
  until one of the following happens:

  +o  There are four recordings scheduled for the same time

  +o  Both slaves are not available

  The scheduler in MythTV checks whether an encoder is available; if a
  slave backend isn't running, its encoder isn't available, so the
  scheduler will look for the next available encoder.  This makes MythTV
  very flexible; slave tuners can come and go, and as long as there are
  enough tuners for what you'd like to record it doesn't matter which
  tuner in particular is going to be used.

  Using this round-robin scheme along with a shared storage directory
  like NFS and enabling the Master Backend Override setting will allow
  you to view content even if the slave backend that recorded a program
  is not available.


  [1m21.13.  What is this transcoder thing, and how do I use it?[0m

  The transcoder re-encodes files from one MythTV format to another.
  The main purpose of the transcoder is to allow users with hardware
  encoders (PVR-250) or systems that can only record in RTJpeg due to
  performance reasons (multiple capture cards, slow system, etc) to
  create MPEG44 streams to save space.

  The transcoder can be used in two ways:

  +o  Automatically re-encode every file once it has completed recording

  +o  After marking commercials, the transcoder can be run manually to
     delete the commercials from the file (thus further saving space)

     The two methods are independent.  The first is an automatic process
     that can be enabled/disabled through the setup program; the second
     is a manual method which must be invoked on each recording
     individually.

  The second method can be used on files that have already been
  transcoded (or files which were are already in the correct format), so
  only the frames immediately following a cut section will be re-
  encoded, resulting in a very minimal loss of quality.

  To enable automatic transcoding, do the following: start the setup
  program under the host-specific settings: set the Transcoder Auto-run
  checkbox

  For either manual or automatic transcoding: start mythbackend start
  mythfrontend select setup, and the Transcoding recording profile.  now
  select either RTJPEG or MPEG-4 (selecting any of the hardware encoders
  will result in the transcoder not working).  set the other parameters
  as you'd like.  For best performance, you should match the audio to
  the 'Default' profile.  If you plan to only use the manual transcoder,
  you can choose to set the video to be the same as the default profile
  too (as long as it is MPEG-4 or RTJpeg)

  Everything should now be setup properly.  If you elected to use the
  Auto-Run feature, the transcoder will automatically launch after each
  recording is complete.  The transcoder thread runs at a low priority,
  so it should not impact any critical tasks or other recordings.

  If you want to manually transcode a program, simply press 'X' while
  watching a recording (you should have already finished marking all
  commercials).  If you change your mind, hitting 'X' again will stop
  the transcoding.

  Once the transcode is complete, mythbackend will replace the old file
  with the new as soon as it is no longer in use.



  [1m22.  Example Configurations.[0m

  This section contains configurations which you may find useful.


  [1m22.1.  Hauppauge PVR-250/350 hardware MPEG-2 encoder.[0m

  [1mNOTE[22m:  THE FOLLOWING DOCUMENTATION IS PROVIDED AS-IS AND IS NOT
  GUARANTEED TO WORK WITH YOUR DISTRIBUTION.  FOR IVTV DRIVER
  ASSISTANCE, SEE THE IVTV MAILING LIST.
  https://lists.sourceforge.net/lists/listinfo/ivtv-devel
  <https://lists.sourceforge.net/lists/listinfo/ivtv-devel>  SEE THE

  <http://ivtv.sourceforge.net/FAQ.html>

  These instructions work for Mandrake 9.1 on a backend machine which is
  hosting a single PVR-250 capture card.

  Install the Mandrake kernel source.  If you are using a different
  Mandrake kernel level (ie, not 2.4.21-0.16mdk as in the example below,
  then alter the [1murpmi [22mcommand appropriately.)


       $ uname -a
       Linux pvr 2.4.21-0.16mdk #1 Fri Apr 11 06:51:54 CEST 2003 i686 unknown
       unknown GNU/Linux

       $ su
       # urpmi kernel-source



  [1mNOTE[22m:  You do not need to recompile your kernel.

  Download the IVTV driver from CVS:


       $ cvs -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/ivtv login
       <enter> as password
       $ cvs -z3 -d:pserver:anonymous@cvs.sourceforge.net:/cvsroot/ivtv co ivtv



  This should create an ivtv directory.  Switch to it and perform the
  following commands:


       $ cd ivtv/ivtv/utils
       $ wget http://hauppauge.lightpath.net/software/pvr250/pvr250_17_21199.exe
       $ su
       # ./ivtvfwextract.pl pvr250_17_21199.exe
       # exit



  The [1mivtvfwextract [22mprogram extracts the firmware required for the card.
  You may want to go to the Hauppauge website and download the latest
  Windows driver if the [1mwget [22mcommand fails.

  Next, compile the driver:


       $ cd ~/ivtv/ivtv/driver
       $ make



  Compile the [1mtest_ioctl [22mprogram:


       $ cd ../utils
       $ make
       $ su
       # cp test_ioctl /usr/local/bin
       # exit



  [1mNOTE[22m: You may get warnings about i2c during the compile.  Ignore them.

  Add the following to /etc/modules.conf:


       alias char-major-81     videodev
       alias char-major-81-0   ivtv
       alias char-major-61 lirc_i2c
       options ivtv debug=1
       options tuner type=2
       options msp3400 once=1 simple=1
       add below ivtv msp3400 saa7115 tuner
       add above ivtv lirc_dev lirc_i2c



  [1mNOTE[22m:  You must specify the tuner type manually.  See
  ~/ivtv/ivtv/driver/tuner.h for a listing of tuners.  In the above
  example, tuner type=2 is a Phillips NTSC.  Use an appropriate tuner
  type for your system and video standard.  The debug=1 parameter on the
  ivtv line actually means less debugging output will be printed.

  Next, copy the files that were compiled in the driver directory into
  the appropriate modules directory:


       $ su
       # make install
       # depmod -a



  Finally, load the ivtv driver:


       # modprobe ivtv
       # exit



  Check that the card is being recognized on the PCI bus:



  $ lspci -v
  <snip>

  00:0c.0 Multimedia video controller: Internext Compression Inc iTVC15 MPEG-2
  Encoder (rev 01)
          Subsystem: Hauppauge computer works Inc.: Unknown device 4801
          Flags: bus master, medium devsel, latency 32, IRQ 11
          Memory at d0000000 (32-bit, prefetchable) [size=64M]
          Capabilities: <available only to root>



  If you don't see your card on the PCI bus, make sure that it's been
  installed in a bus-master slot.  For some motherboards, only the PCI
  slots closest to the AGP slot are bus-mastering.

  Check that the ivtv driver has created a new video device:


       $ ls -l /dev/v4l/vi*
       crw-------    1 mythtv   sys       81, 224 Dec 31  1969 vbi0
       crw-------    1 mythtv   sys       81,   0 Dec 31  1969 video0
       crw-------    1 mythtv   sys       81,  32 Dec 31  1969 video32



  In this case, the ivtv device is video0.

  Go into setup/setup on the machine hosting the hardware MPEG-2 card.
  When you add a new capture card, ensure that you are using the video0
  device.

  [1mNOTE[22m:  As of 2003-04-25 the ivtv driver does not support VBI, so
  closed-captioning is not available.

  Leave the VBI device, audio device and audio sampling rate limit at
  the default values.  Change the default input to an appropriate
  setting for your configuration.  Change the card type to "Hardware
  MPEG Encoder Card" and press ENTER.

  The remaining setup is just like a standard V4L card; define a video
  source if you have not already done so, and assign the video source to
  a video card input on the Input Connections screen.

  Some people report issues with the ivtv module not being loaded when
  required by MythTV.  To get around this, you can [1mmodprobe [22mthe ivtv
  driver before using it.  The simplest technique is to add the [1mmodprobe[0m
  command to /etc/rc.d/rc.local:


       # echo "/sbin/modprobe ivtv" >> /etc/rc.d/rc.local



  [1mNOTE[22m:  some people complain that their PVR-250/350 card is not
  capturing audio.  The most likely source for this is that your system
  is not loading the correct msp3400.o file; ivtv uses a custom
  msp3400.c, and if the resulting module isn't loaded you will not get
  sound.  Switch to your /lib/modules directory and rename the existing
  msp3400.o file, then copy the msp3400.o from the ivtv driver directory
  and re-run [1mdepmod[22m.  If that still doesn't work, then check the ivtv
  mailing list for more information.  You may wish to perform an
  [1mupdatedb [22mas root and then do a locate msp3400 to find all the
  msp3400.o.gz files that may be on your system.  For example, Mandrake
  has a msp3400.o.gz in the 3rdparty subdirectory which will take
  precedence over the custom version created by ivtv.  You can check if
  you have the correct msp3400 loaded by typing (as root): modinfo
  msp3400 | grep "parm: *standard".  If you don't get a line that says:
  "parm:        standard int", then you're not loading the correct
  msp3400.

  Check to ensure that you're loading the correct msp3400 module.



       # modinfo msp3400
       filename:    /lib/modules/2.4.22-9mdk/kernel/drivers/media/video/msp3400.o



  Check that the path is correct for your kernel version, and that the
  driver being loaded is in /media/video and not some other directory.

  [1mNOTE[22m:  Some people report "ghosting" issues with their PVR-250s, where
  there is a faint copy of whatever is on the screen appearing to the
  right of the image.  If you have this issue, it's fairly obvious.
  This is a firmware issue, apparently.  There are two ways around this:

  1. Run at 720x480 resolution

  2. Turn off DNR

  To turn off DNR, add the following to your rc.local:


       /path/to/ivtv/utils/test_ioctl --set-codec-params=dnr_mode=0,dnr_temporal=0



  [1m22.2.  Hauppauge PVR-250 remote and MythTV's native LIRC support.[0m

  [1mNOTE[22m:  THE FOLLOWING DOCUMENTATION IS PROVIDED AS-IS AND IS NOT
  GUARANTEED TO WORK WITH YOUR DISTRIBUTION.  FOR LIRC DRIVER
  ASSISTANCE, SEE THE LIRC MAILING LIST.

  These instructions work for Mandrake 9.2 on a frontend machine which
  is hosting a single PVR-250 capture card using MythTV's native LIRC
  support.

  First, you need to ensure that you've installed the kernel source
  appropriate for the kernel that you're running.  In this case, we're
  using kernel 2.4.22-9, so when installing the kernel-source ensure
  that you've got the correct version.



       $ su
       # uname -a
       Linux frontend 2.4.22-9mdk #1 sam sep 13 06:54:11 CEST 2003 i686 unknown
       unknown GNU/Linux
       # rpm -qa|grep kernel-source
       kernel-source-2.4.22-9mdk


  If you've already installed LIRC from the Mandrake packages, it's
  going to be version 0.6.6, and that won't work.  Uninstall it:


       $ su
       # urpme lirc lirc-remotes liblirc-devel
       # rm -rf /dev/lirc*
       # exit



  Check to ensure that you don't have other versions of lirc modules and
  programs on your system:


       $ su
       # updatedb
       # locate lirc_i2c|grep `uname -r`
       /usr/src/linux-2.4.22-9mdk/3rdparty/lirc/lirc_i2c.c
       /lib/modules/2.4.22-9mdk/kernel/3rdparty/lirc/lirc_i2c.o.gz

       # locate lirc_dev|grep `uname -r`
       /usr/src/linux-2.4.22-9mdk/3rdparty/lirc/lirc_dev.c
       /usr/src/linux-2.4.22-9mdk/3rdparty/lirc/lirc_dev.h

       /lib/modules/2.4.22-9mdk/kernel/3rdparty/lirc/lirc_dev.o.gz

       # locate irw|grep "/usr"
       /usr/bin/irw
       /usr/local/bin/irw
       /usr/local/man/man1/irw.1

       # locate lircd|grep "/usr"
       /usr/src/linux-2.4.22-9mdk/3rdparty/lirc/lircd.conf.RM-050
       /usr/share/man/man8/lircd.8.bz2

       /usr/sbin/lircd
       /usr/local/sbin/lircd
       /usr/local/man/man8/lircd.8

       # locate irxevent|grep "/usr"
       /usr/share/man/man1/irxevent.1.bz2
       /usr/share/doc/lirc-0.6.6/html/irxevent.html

       /usr/local/bin/irxevent
       /usr/local/man/man1/irxevent.1



  As you can see, there were a number of different versions of lirc
  already installed on this system.  They must be removed.  We don't
  care about the source code or the man pages, only the executables and
  the kernel modules.


       $ su
       # rm -rf /lib/modules/2.4.22-9mdk/kernel/3rdparty/lirc
       # rm -rf /usr/sbin/lircd /usr/local/sbin/lircd
       # rm -rf /usr/bin/irxevent /usr/local/bin/irxevent
       # rm -rf /usr/bin/irw /usr/local/bin/irw


  Download the lirc-0.7.0pre2 tarball:


       $ wget http://lirc.sourceforge.net/software/snapshots/lirc-0.7.0pre2.tar.bz2
       $ tar -xjf lirc-0.7.0pre2.tar.bz2



  Mandrake now includes i2c version 2.8.0 which changes the semantics of
  some low-level calls.  You will need to patch LIRC in order for it to
  work correctly.  Download the patch and install:


       $ cd lirc-0.7.0pre2
       $ wget http://delvare.free.fr/i2c/other/lirc-CVS-i2c-2.8.0.patch
       $ patch -p1 < lirc-CVS-i2c-2.8.0.patch



  Next, run the LIRC setup program:


       $ ./setup.sh



  Select "1" (Driver configuration), then scroll down to "5" (TV Card),
  press ENTER, then scroll down to "f" (Hauppauge TV card) and press
  ENTER again.  Once back at the main menu, press "3" for Save and run
  configure.

  If your build environment is ready, LIRC will create a Makefile for
  you.  Switch to root and compile:


       $ su
       # make
       # make install



  As a part of the make install process, LIRC will create the
  appropriate device for you in /dev.  Check to make sure:


       $ ls -l /dev/lirc*
       crw-r--r--    1 root     root      61,   0 Sep 18 15:36 /dev/lirc
       srw-rw-rw-    1 root     root            0 Sep 18 15:38 /dev/lircd=



  Your modules.conf file should have already been modified if you've
  followed the instructions ``above'' for installing the PVR-250.
  [1mmodprobe [22mthe lirc_i2c driver, run the [1mlircd [22mprogram and then check

  To check that your remote is working correctly, run the [1mirw [22mprogram
  and start pressing buttons.  If nothing is happening, you must begin
  troubleshooting.  Things to check:

  +o  Are there batteries in the remote?

  +o  Does the remote work?  You may be able to see the flashes of IR
     coming from the remote if you look at it with a video camera.

  +o  Is the IR dongle cable plugged in?

  +o  Did you remove all of the old LIRC device drivers?  Run "updatedb"
     as root, then "locate lirc_i2c".  The only lirc_i2c should be the
     one in the misc/ directory for your kernel version.

  +o  Did you run depmod?

  +o  Is your modules.conf setup correctly?

  +o  Did you modprobe lirc_i2c?

  +o  Did you run lircd?

  +o  Do you have an /etc/lircd.conf?

  +o  Is /dev/lirc a character mode file, major 61, minor 0?  Is it
     readable by all groups?

  +o  If you think you may have had old LIRC device drivers you may need
     to reboot to ensure that they're totally out of the system.  Try
     running modprobe -r lirc_i2c as root first, then modprobe lirc_i2c
     and try again.

  +o  What path does modinfo lirc_i2c and modinfo lirc_dev show?  It
     should be in /lib/modules/{your kernel version}/misc/

  If none of the above works, and [1mirw [22mstill isn't showing keypresses,
  then you will need to ask your question on the LIRC list.

  Assuming that [1mirw [22mis showing keypresses, you can continue: To enable
  native LIRC support within MythTV, you will need to modify your
  settings.pro file and recompile.  Your settings.pro should look like
  this:



  # Native lirc support
  CONFIG += using_lirc
  EXTRA_LIBS += -llirc_client



  Recompile and install:


       $ make distclean; make
       $ su
       # make install



  If you're not using native LIRC support, ensure that the button names
  that come up with [1mirw [22mmatch the ones in the .lircrc file in your home
  directory.  Note that if you are not using native LIRC support, the
  .lircrc file is in your home directory and has a "." as the first
  character.

  Since we're using native LIRC support within MythTV, copy the
  configfiles/hauppauge-lircrc-nativelirc file into your .mythtv/
  directory and call it lircrc.  It has a slightly different format than
  what you would use if you were using [1mirxevent[22m.  Also note that it is
  in your .mythtv directory and does [4mnot[24m have a "." in the filename.



       $ cp configfiles/hauppauge-lircrc-nativelirc ~/.mythtv/lircrc



  Add the commands to load the LIRC device drivers and start [1mlircd [22mto
  your rc.local:


       $ su
       # echo "modprobe lirc_i2c" >> /etc/rc.d/rc.local
       # echo "/usr/local/sbin/lircd" >> /etc/rc.d/rc.local
       # exit



  You should now have native LIRC support within MythTV.


  [1m22.3.  Logical Volume Manager (LVM).[0m

  LVM greatly increases the flexibility you have in managing your
  storage than traditional physical partitions. This section will
  provide some brief notes on how to use LVM to create storage space for
  your video files and how to add additional disk space in the future.
  There's lots more that can be done with LVM, so check the LVM HOWTO
  http://tldp.org/HOWTO/lvm-HOWTO/ <http://tldp.org/HOWTO/lvm-HOWTO/>
  document for details.

  Make sure your kernel configuration includes LVM support or that it's
  available as a module. Today, most vendors include this by default.
  You'll also want to ensure that you have a copy of the LVM utilities;
  check your distribution, or get the latest versions from
  http://www.sistina.com/products_lvm.htm
  <http://www.sistina.com/products_lvm.htm> and build them manually.

  Check that the [1mvgscan [22mprogram is being run at some point during your
  boot sequence - most distributions do this by default. Look for a
  message during boot up that looks like this: vgscan -- reading all
  physical volumes (this may take a while...)

  LVM uses a few concepts you should be familiar with before starting.

  +o  PV (Physical Volume).  The actual partition on the hard drive.

  +o  VG (Volume Group).  The aggregation of all the PVs make a VG.

  +o  LV (Logical Volume).  Subdivision of the pool of space available in
     the VG into individual chunks, like /usr, /var/video, etc.

  The following example assumes that you want to create a LVM partition
  from a chunk of space in /dev/hda5, using a reiserfs filesystem and
  mounted on /var/video. You later decide to extend this filesystem by
  adding a new disk: /dev/hdb.

  You need to create at least one LVM partition for a physical volume.
  Use [1mfdisk [22mor your favorite partition editor to set the type to LVM
  (0x8e). If you're using an entire disk, create one big partition
  rather than using the device itself. e.g. use /dev/hdb1 not /dev/hdb.

  # fdisk /dev/hda .... create partition 5, save partition table and
  reboot if you have to

  Create the LVM physical volume from the partitions (repeat if you have
  multiple partitions to use):


       # pvcreate /dev/hda5



  Create a LVM volume group out of this physical volume called
  "VGforMyth" that is allocated in chunks that are a multiple of 64MB


       # vgcreate --name VGforMyth -s 64m /dev/hda5



  Create a logical volume of 20GB called "video" and then create the
  reiserfs filesystem and mount it:


       # lvcreate --name video --size 20G VGforMyth
       # mkreiserfs /dev/VGforMyth/video
       # mount /dev/VGforMyth/video /var/video



  Now create a 5GB volume for mythmusic files if you like:


       # lvcreate --name music --size 5G VGforMyth
       # mkreiserfs /dev/VGforMyth/music
       # mount /dev/VGforMyth/music /var/music


  Display the volume group status: # vgdisplay -v

  Now, lets suppose you want to add a 60GB hard disk to the system as
  hdb and allocate 50GB of it to video storage.

  First, create a single partition /dev/hdb1 covering the whole disk and
  make it type 0x8e using your partition editor.

  # fdisk /dev/hdb .... create partition, set type, save and reboot if
  it says you have to

  Create the new LVM physical volume:

  # pvcreate /dev/hdb1

  Add the new physical volume to the volume group:

  # vgextend VGforMyth /dev/hdb1

  [1mNOTE[22m:  You may get errors at this point stating that there are no
  physical volumes available for adding to the LV, even though you know
  for a fact that there are.  You may need to specify the physical
  volume in the /dev/ide/host/bus/target/lun/etc format.

  Once you've completed one of the following two procedures, use [1mdf [22mto
  check that you've got more space.


  [1m22.3.1.  ReiserFS[0m

  Make the logical volume used for video bigger:

  # lvextend --size +50G /dev/VGforMyth/video

  Unmount, resize and remount the filesystem.  Technically, you don't
  need to unmount and remount the ReiserFS.


       # umount /var/video
       # resize_reiserfs /dev/VGforMyth/video
       # mount /dev/VGforMyth/video /var/video



  [1m22.3.2.  ext2 or ext3[0m

  LVM comes with a program called [1me2fsadm[22m.

  Unmount, resize and remount the filesystem.  The filesystem [4mmust[24m be
  unmounted during this procedure.


       # umount /var/video
       # e2fsadm --size +50G /dev/VGforMyth/video
       # mount /dev/VGforMyth/video /var/video



  [1m22.4.  Advanced Partition Formatting.[0m

  MythTV creates large files.  The partitions that your distribution
  sets up for you may not be optimized for large files.  Using ``LVM''
  in conjunction with the following techniques can be quite useful.

  [1m22.4.1.  Ext3[0m

  With Ext3, your biggest gain is that in case of a crash and reboot you
  don't have to wait very long for your partition to be remounted.  With
  Ext2, the [1mfsck [22mmay take a long time to run on multi-gigabyte
  partitions.

  When formatting the partition, the following command line should be
  better than the default.  This example assumes that /dev/hdb1 has
  already been created using [1mfdisk[22m.  If you're using LVM, /dev/hdb1 may
  be something like /dev/VGforMyth/video.


       # mkfs.ext3 -T largefile4 -m 0 /dev/hdb1



  The "-T largefile4" option creates one inode per 4 megabytes.  The "-m
  0" (zero, not "oh") parameter sets the amount of spaced reserved for
  root to zero. By default, this is 5%, which on a multi-gigabyte drive
  is a lot of reserved space.

  You may also modify some aspects of a filesystem such as the reserved
  block percentage after it has been created using the [1mtune2fs [22mprogram:


       # tune2fs -m 0 /dev/hdb1



  You can check on your filesystem using the [1mdumpe2fs [22mprogram.  See the
  [1mman [22mpage for details.
