I´ve done a project using Vegas 7. All is ready, the audio is in complete sync with the video confirmed by viewing in the preview screen on Vegas 7.

I choose "render as" and AC3 stereo file 192kbps. No biggie, all goes well and i end up with an AC3 File.

The problem is that while working in DVDa, i import the video, and after i import the audio. While in the preview screen of DVDa the audio is out of sync!!!?!?

Can anybody help me?

BTW: I´ve tryed to create the DVD using DVDa but the audio is out of sync also.

Have you tried it with PCM sound and see if that makes a difference?
Have you tried using the Batch script so it does it automatically?

IS DVD-A set to PAL?

I have never had it with my DVD-A

Please render a small piece of your original project to AVI and then repeat the AC3 and MPEG render and create a DVD thru' DVDA.

If you DO have another DVD authoring package, I would be tempted to test the old AC3 and MPEG thru that too?

I create a finished AVI of the WHOLE project - one BIG file - and then render that out to AC3 and MPEG. That way I just KNOW that both files are the same length.

Synch drift - is it drift? - is a real pain in the bottom. If it is just OUTTA Synch from strat to finish then I'd be looking at FILE lengths ( hence that above) and NOT getting the AC3 sitting correctly UNDER the video for authoring.
