I am using a AverTV DVB-T 771 Card beside my PVR-350. I have a lot of trouble 
with the bt878 driver if both card running (recording). 
...
Nov  7 14:17:16 localhost kernel: bt878(0): irq FBUS risc_pc=1e41a210

The result is a heavy damaged mpeg stream.

Maybe other DVB Cards (or Drivers ;-)  will work better.

I tried. It work :-( If I am watching live from the dvb-t the situation will 
become worse.

Beside I am currently not happy with the PVR-350 TV-Out. If it just play a 
recording the picturequality is very nice and the motion is smooth. But if I 
start fastforwarding or rewinding the system will die after after a while 
(ok, I am not a very patient person, so fastforward is very important for 
me ;-)
Finialy I end up with continue using the TV-Out of my nvidia card. 
picturequality and motion could by better, but everything is rock solid with 
exception of the bt878 issue.
