Audio sync problem with DVD2DVD-r

[Pntgrd]

I have been using DVD2DVD-r to do my backups for a couple of years and I have never ran into this. When doing a backup of The Ten Commandments - Disc 2 I am getting a sync problem. I have never ran into this and have done hundreds before. I did notice one funny thing but don't know if it is related. I have always copied the Chapter info from the Info.txt file and then imported the Chapters while authoring with DVD-Lab. This disc had some strange time stepping to start in it and when importing it bells actually sounded at every chapter point until it got to what would be the actual chapter points, very strange. I tried removing the strange points and that at least got rid of the bells but still sync problems. I then opened the Info.txt file and found it siad there was a -67ms audio offset so I tried a 67ms offset in DVD lab which helped some. I have even tried a total reencode but still the same results. Any suggestions? Or do I need to keep trying different offset values until I hit the magic number? TIA for any suggestions

Hi!
I've been using DVD2DVD-r too for a long time with no problems.
I'm having the same problem with two DVDs, namely The Fast & the Furious: Tokyo Drift and Flight Plan. I've noticed the strange chapter info you mentioned in these DVDs too. I use IFOedit for multiplexing.
If I encode them with Nero Recode alone they are finely synchronized. (but the quality sucks!)

Does anybody know how to resolve this issue?
