I know this has been covered numerous times, but I'm a little lost with this one.

Basically I have a DivX AVI coded at 25fps and 48000 MP3 128khz for audio that I am trying to convert and author to DVD.

In the past when I was making only VCD's, I would simply save the audio as a wav with Virtual Dub, load the avi for video in TMPGEnc and the wav file for audio, select 29.97 and presto! I would have a perfectly fine mpeg1 file that was perfectly in sync.

Now, when I try to follow the same steps for DVD using the NTSC DVD template included with TMPGEnc, I get the 2 seperate files, .m2v and .wav that have to be muxed in my authoring program.

So I mux (author) with DVD-lab and when I test the resulting VOB, the audio and video are out of sync (more so towards the end of the movie, of course).

To make things even more confusing, I have a similar AVI file with which I followed the same steps and it came out fine! No sync problems whatsoever. The only difference is that it was originally encoded with 44100 audio.

Is there something I should be doing differently with DVD creation than I was doing with VCD creation to ensure I get sync?

Are there some other settings that I should be paying attention to?

Thanks in advance,

Tim
