Audio Synch Issue with Combined DVD

I recently combined my Gangs of New York disc 1 and 2 using handbrake and dtox. The movie plays fine in Nito but in atvFiles there is an audio synch problem. When the movie gets to the halfway mark (where disc 2 would begin) the audio is out of synch with the video.

Has anyone merged 2 dvds such as LotR or GoNY with any success?

Hmmmm… I haven’t tried the movies you mentioned - But I combine use D-Vision to merge all my .AVI files… and haven’t come accross your issue.
