I'll do this (around 400 MB i guess) as soon as my VDR Box is reconnected to
my network ... Hopefully tomorrow - but thats another story!

No.

I played thim with the -vc mpegpes switch through the DVBs Hardware and it
wasn't in sync, too :-(
But playing them in VDR ist just fine - the same if converting them with
PVAstruento (a tool for Demuxing DVBs recording and taking care of the a/v
sync according to the PTS info) and playing in WMP
