ffmpegX is great, but the only lingering problem I seem to always have
is that of audio/video sync. Basically, I have an AC3 audio track and a M2V track. Usually, I need to use ffmpegX to reencode the M2V at a
lower bitrate (MPEG-2) to fit on a single DVD-R. I finish the encode and then, almost without exception, the new M2V and AC-3 file are improperly synced when previewed in and even when exported from DVDSP. I have tried many permutations of the settings, but none seem to work reliably.

What are the latest suggestions on getting audio/video to sync in an
M2V/AC3 environment?

Here's a way that I found almost gets it right, but it seems a little redundant. I take the large M2V (which is usually at 23.98 fps) and run it through MPEG telecine. Then I reencoode with ffmpegx to a lower bitrate. ffmpegX detects correctly that the source is telecined. It writes output as a 23.98 fps MPEG2. I then run the new MPEG2 through MPEG telecine and then import into DVDSP. Then the audio/video sync problem seems to be minimized.


Thanks.
