I have the same problem using an ATI HD4200. I thought it was that the
TV Channel didn't have enough signal, as this only happens while
I think is due to that it change mpeg files in the same recording and it
is matter of buffering but don't know the solution.
BTW I have a Nova T-500 and if I set the PVR-530 (ivtv) as the default
option for output profile the quality of the image is great but after 20
min, the recording playback is restarted.
Now I'm using xvmc-blit as the renderer and I have the same problem as Rama.
Any help is more than welcome as losing 3 min of my recordings is a
pitty (actually always following the murphy law ;))
