Sorry to reply to my own post yet again. I think that I've found why the picture quality is poorer with the PVR-500. The temporal_filter is being set to 8. The question is why, as I've not yet tracked down the reason. It's quite possible that I've screwed up something in my own code mapping the old codec information to the v4l2 external controls. Is it possible that the driver sets the temporal_filter during other operations, such as set format? Why is this only being set with the PVR-500 and not with the PVR-350? Any hints?
