I was using a Athlon500 before with a PVR-350 and a PVR-500, 512MB Ram 
and a FX5200 which worked fine for livetv and simultanious recording on 
a AMD-chip based mobo. 2 recordings and watching 1 was ok as well, 2 
recordings and live wasn't.
It might be your PCI-bus though, especially if your using a VIA-based 
solution, they're notorious known for bad performance and errors.

Your system should be able to watch and record at the same time, as the 
processor is quicker than mine was. I'd check the motherboard, and check 
  which deinterlacing you're using, that might make quite a difference 
as well.
