Well I finally got MythTV working.
It’s pretty cool. A proper hard disc recorder on your computer. It’s really meant to be used as a standalone unit, but mine has just been setup on my workstation, since I have a dammed cool 2405fpw Dell24″ monitor 🙂
The Gentoo Wiki page was very useful in getting this set up. Especialyl the bit in getting ALSA and especially an ALSA mixer device to work.
