I suspect tcprobe. Please try to find the a/v timestamp difference using
(e.g.) mplayer -mc 0 -autosync 30, using the +/- key. I used to do that,
and it worked fine.

Another blunt axe solution is to use projectx to demux, it will make
sure
the timestamps start both at zero, discarding some frames to align.
