Thanks.  But gstreamer also lost the sync at 160 seconds (like
ffmpeg2theora).

Ah ha.  That works sometimes.  "mencoder $file -ovc lavc -lavcopts
vcodec=ljpeg -oac copy -o mencoder.avi" generates a giant correct
fixed-fps avi file.  Oddly, "ffmpeg2theora mencoder.avi" doesn't quite
work.  It generates a .ogg file where the video starts a second after
the audio, so the whole thing is out of sync right from the beginning.
But "theora-encoder mencoder.avi" (avi -> yuv -> example_encoder)
works.

Thanks for your help.
