There is one more issue, that seems to be related. On some recordings, 
here RTL Television with AC3 playback, sometimes single frames seem to 
be skipped during playback. I watched a recording of "Alarm für Cobra 
11" yesterday and could identify at least 6 little jumps.

I have isolated a 20 MByte part of this recording where this effect was 
clear to see - I can send it by seperated mails or upload it somewhere 
if someone gives me an URL.

The weird thing: Playing those isolated scenes does not show the effect 
as people can see if they play the whole recording from the beginning, 
but rewinding the short clip to a certain point makes it possible to 
reproduce the problem. And again: This just happens when playing back 
the AC3 audio track.

With kind regards

Jörg
