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
- XvMC but I'm not really sure if it helps
- MythMusic
- MythGallery
- MythDVD using xine as an external player
- MythWeb on Jetty rather than apache including the WAP version on the BlackBerry!
- Using irexec to restart Myth, including with a different Layout to switch between the Projector and TV
What's not
- 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. (So far so good on the Gigabyte card since Aug 2006).
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, Samsung LCD. See also the tips for the NVidiaProprietaryDriver
Option 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.
Option "UseEDIDDpi" "false" is important for the Samsung television otherwise you get really small fonts!
There are two layouts, the default uses outputs via VGA to a Samsung LCD television, the second uses DVI to the PE8700 projector.

0.19.x fixes info

to compile) - Xine external DVD/video player
- XvMC ( with Bob de-interlacing for HD channels. Have to manually turn it off for SD stuff).
