I had audio sync problems doing the mencoder -ovc divx4 -oac copy as well.  The way I got around that was to do the process below for making VCD's.  first do the mencoder -ovc copy -oac copy.  Then use the resulting AVI to encode to the format you'd like it in.  I haven't tried doing it to divx, just using the mencoder script.

Okay I've tried both:

	mencoder -ovc copy -oac copy
	mencoder -ovc divx4 -oac copy

and both give me audio/video out of sync (mencoder reports duplicate
frames).  I've also tried mencvcd with both of the above.  My recordings
are 640x480 MPEG-4 3300bps, min qual 1, max qual 10, max diff 3, scaled
for resolution.  Audio is 32000 Hz MP3 (quality 7).

It would appear that, contrary to reports in this thread, mencoder is
not making up for duplicate frames.  Either that, or the fact that my
audio is 32000 Hz vs. 44100 is causing some problems.

Any help?

Thanks in advance,
