Hello

I have an already authored DVD with nice menus and chapters but unfortunately the audio is out by 200ms.

Is there any way to correct the audio sync in the VOB without having to re-author the dvd? (Since I won't be able to recreate the menus.)

How about:
- demuxing to m2v and ac3,
- correcting the audio sync,
- re-authoring without menus, and then
- replacing the old VTS_01_1.VOB with the new one.

Will that work?

Any help appreciated.
