HI!
Thanks for your fast reply.

Using mplayer (libmpeg2) causes pixelization for a short moment after

ffmpeg to libmpeg2, it behaves the same (no error messages, but
pixelization).
This is a libmpeg2 feature. It is more optimized for best possible speed
rather than quality. If you want quality then use ffmpeg for decoding.
Funny thing is, that libmpeg2 has no such problem with MPEG2 recordings
from an analog card (Hauppauge PVR-250).
Also it is very likely that anything you save off a dvb device will have
some errors in it. This can be caused by so many different things you
can't really do much about it. Most of these are so small that you won't
even notice they're there unless your're using a really badly behaved
decoder. Sometimes there are errors and you just have to live with it.
I only had one visible error so far, so that's OK.
What I do not understand is, that I get those error messages from the
ffmpeg decoder for most of the recordings when skipping through it, but
czap says 0 UNC errors, even when running for a long time.
All this led me to the conclusion, that something is permanently (not
only every x minutes or so) wrong in the MPEGs and that I can/should do
something about it. But I could be wrong.
Probably the best thing you can do about it is to run the captured mpegs
through a program that removes the broken parts such as projectx.
OK.
Thanks!
Thomas
