The recent ivtv 0.4.0 driver coupled with the new xdriver has really 
cleaned up XV support on the 350. It'll burn more CPU than hardware 
decoding, but the playback should be quite smooth.
Having said that, I no longer use my PVR 350's TV OUT. I use an nvidia 
5200 instead because I play games and use the hardware GL support.
