Good to know that others have the same issues. I get delays between
+250ms and -200ms.

This doesn't work correctly for -oac copy and ac3 streams. The produced
file plays fine with mplayer, but with no other player (I think I
remember xine worked as well). Media player classic (guliverkli)
complains that there's no audio, VirtualDub even crashes as soon as
anything is to be done with audio.
FWIW, -demuxer mpegts (default) works (modulo the delay).
Is this a known issue (actually two known issues), or should I upload a
sample?
Thanks
Matthias
