I have a PVR-350 and a PVR-150 running on FC8, and the recordings are
seemingly better [to my untrained eye] on the PVR-350. I did have
ghosting on the capture cards until I set the temporal filter to 0.

# Get rid of IVTV ghosting
v4l2-ctl --set-ctrl temporal_filter=0


I don't know if this helps the OP, but I thought I'd bring it up.
