Let me just start by saying MythTV rocks. I was keeping track of where I was at with Myth on my home wiki, but then figured I might as well share it here!

My Setup
Combined FE/BE.
Hardware
- AMD S754 Athlon 64 3700+
- Gigabyte S754 GA-K8VM800M
- 1GB Ram
- 320GB Western Digital 7200rpm 8M Serial ATA HDD
-
Albatron FX5200LP 128M 8x Video Card with DVI output. - Gigabyte FX5200 128M 8x Video Card with DVI output.
- DVICO FusionHDTV Hybrid Tuner
- DNTVLive LP Tuner
- DVICO FusionRemote
- BenQ PE8700 DLP Projector
Software
- Ubuntu Dapper (upgraded from Breezy server install)
- Kernel 2.6.15-27-amd64-k8
- v4l-dvb-0.9 drivers patched to handle vendor/device codes being the same between 2 different devices!! (Many thanks to Chris Pascoe for getting the DVICO card going)
- NVidia amd64 version 8774
- lirc version 0.8.0 (Dapper upgrade changed device from
/dev/usb/hiddev0
to/dev/hiddev0
- Ratpoison window manager
- MythTV 0.20.x fixes branch
What's working for me
- Live TV/TV recording Free to air HD/SD (from Sydney, Australia). Both tuner's simultaneously.
- AC3 passthrough including 5,1 surround
- XMLTV grabber from the OZTivo site
- MythMusic
- MythGallery
- MythDVD using xine as an external player
- MythWeb on Jetty rather than apache
- Using irexec to restart Myth, including with a different Layout to switch between the Projector and TV
What's not
- XvMC not sure if this is an NVIDIA driver thing or 0.20 but bad stuttering and "audio buffering" messages in the logs
- The Gigabyte FX5200 card does not do PAL output properly, as it renders in B&W. Fortunately my TV autodetects NTSC colour.
- The Albatron FX5200 card has been fingered as the cause of my DVI problems on my projector. Apparently it freaks out a PCB component causing the EDID data to become corrupt. (1 day and counting, so far so good on the Gigabyte card).
What more do I want to do
- I'd like MythMusic to use MythGallery as a visualisation!
- More cleanup of MythGallery thumbnail code. (Thumbnail cache is unnecessary if EXIF thumbnails are available in the images themselves)
Useful config info
xorg.conf for PE8700 and TV-Out
ExactModeTimingsDVI is important for the projector. This is the main detail, the driver autodetects the connected display and will use the Projector (DFP) in preference to TV-Out.
Section "Device" Identifier "FX5200[0]" Driver "nvidia" BusID "PCI:1:0:0" Screen 0 #Not sure of the effect of this Option "NvAGP" "3" EndSection Section "Screen" Identifier "Screen[0]" Device "FX5200[0]" Monitor "Either" DefaultDepth 24 SubSection "Display" Depth 24 Modes "1280x720" "720x576" "800x600" EndSubSection EndSection Section "Monitor" Identifier "Either" Option "DPMS" #Option "UseEDIDFreqs" "true" Option "ExactModeTimingsDVI" "true" Option "RenderAccel" "true" #Option "TVStandard" "PAL-B" Option "TVOutFormat" "COMPOSITE" Option "TVOverScan" "0.5" EndSection
Because the projector still signals that it is "connected" during its 2 minute warm down phase I have a second ServerLayout that points to a Screen section that specifies
Option "UseDisplayDevice" "TV"
in case I am in a hurry to switch back to the TV.
.asoundrc For ALSA digital audio out
pcm.!default { type plug slave { pcm "spdif" rate 48000 format S16_LE } }
/etc/inittab entry to auto login the mythtv user

.profile to start X from the auto login, also starts irexec.

.xsession To start MFE and Ratpoison

.ratpoisonrc

script to restart MythTV via irexec.
#!/bin/bash pkill -t tty1 -u mythtv mythfrontend if [ $# -gt 0 ] ; then echo $1 > $HOME/.xlayout fi sleep 1 pkill -u mythtv irexec pkill -9 -t tty1 -u mythtv
the .lircrc file (buttons as per the DVICO remote, which I think are now standard in the lirc distribution)
## irexec # Bounce this tty begin button = power_onoff prog = irexec config = /home/mythtv/bin/ir_power_onoff.sh & end #Run myth-setup begin button = cpf prog = irexec config = /home/mythtv/bin/ir_myth_setup.sh & end #Bounce the tty, set the TV layout. begin button = tv_onoff prog = irexec config = /home/mythtv/bin/ir_power_onoff.sh TV-Only & end
