Revision as of 06:11, 29 March 2008

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

& 500GB 7200rpm SATA driver

  • 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 0.21-fixes branch


What's working for me

  • Live TV/TV recording Free to air HD/SD (from Sydney, Australia). Both tuner's simultaneously AND multi-rec
  • Video profile Standard + Bob2 deinterlace (anything else uses excessive CPU, XvMC will not upscale smoothly to the TV resolution)
  • AC3 passthrough including 5,1 surround
  • Shepherd XMLTV grabber
  • 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.

(the Gigabyte card lasted from Aug 2006 to Dec 2007. Fortunately the new nvidia driver allow you to override the EDID from the device with a file...).

Useful config info

xorg.conf for PE8700, Samsung LCD. See also the tips for the NVidiaProprietaryDriver

Option ExactModeTimingsDVI is important for the projector. Option "UseEDIDDpi" "false" or some equivalent control of DPI is important for the Samsung television otherwise you get really small fonts (fixed in 0.21)

There are two layouts, the default uses outputs via VGA to a Samsung LCD television, the second uses DVI to the PE8700 projector.

Section "ServerLayout"
