This also may be an issue with DGIndex reporting an incorrect delay due to garbage at the beginning of the first VOB, since AutoGK uses DGIndex. When you get to the step where DGIndex is running, click on DGIndex and hit ESC to stop it. then follow the steps as outlined in
this discusssion.
Then save the DGIndex project and AutoGK will resume from where it left off, hopefully with a correct audio synch.
