My PVR experiences:

I'm using a PVR-350 (on XP sorry but DVD authoring was easier): rule  
of thumb for CPU needs,  is if you have hardware mpeg-2 compression,  
you can get by with a 700- 800MHz CPU (or faster)- there will only be  
about 5% CPU load if you avoid the software mpeg compression.  Also  
should avoid VIA chipset mainboards, although there is a patch to  
help, the VIA chipset will be laggy.

I have the  MX400 card as well but don't like the video-out as well  
from it as that from the 350 itself; although using the TV-out on the  
350 limits software menu display a little (I use gbpvr, which does  
have better support than other solutions).

I looked into the netbsd/MythTV solution as well but it didn't look  
easy to do/ not completely supported/hard to tell my wife how to take  
clips from PBS programs to use clips in her teaching as either mpeg  
or DVD-R (the last was a major issue!).
