Have you tried increasing the bitrate? Go nuts and see if it makes a
difference. I use 6400/8000 which is much better than the analog signal out
of a digital satellite set top box.
Use 720x576 and Stream Type: 'DVD-Special 2' in case you ever what to put it
on a dvd.
On every boot do a 'ivtvctl -c dnr_temporal=0' to turn off temporal filtering.
One other thing I did was turn up the contrast and colour by 5%. While using
Live TV on the PVR-x50, press 'g' for the recording controls.
