I hope this explanation is better: If I let mplayer play the video from
the beginning to end without skipping with cursor keys/pgup/pgdn the
video and audio runs fine. After skip the sound gets broken and loops
forever certain short part of video (not from the skip point audio
track). The produced avi file is therefore somehow broken. The original
00x.vdr files play perfectly with mplayer. (I think I should try also
xine for playback if mplayer is erroneous)

Shorter DVB-T clips which are preprocessed with PVAs can be
browsed/skipped with mplayer controls without problems.

OK! Wine is a pain to set up :^)

Mencoder produced about 1400 skipped frame messages for this movie. 

From the other mails in this thread it seems that I could try to hack
this script to use PVAs with ext3 filesystem and 2.4.x kernel. Hopefully
native solutions will work in the future, Wine is a pain to set up :^)
