I'm currently evaluating SageTV and it looks really good. It does however struggle on a [email protected], which is a bit disappointing. Its not a freebie though. That said, I made a MythTV computer running under Linux and that's working fine - even with an older P4. Its not exactly "family" friendly insofar as it requires the "geek" hat to programme. I recorded a programme last night and played it back with much joy. Still ironing out a bug with the soundcard though. It likes the sound built into my computer but not the SB2 plugged in the slot. A bit annoying as I lose my surround sound capability on playback. I'm sure I'll figure it out eventually (see geek hat above).
