Maybe this helps
Pirates of the Carribean 2 (PC2) was my first every DVD to copy using
DVDFab. I successfully copied the 1st chapter of Perl Harbour and then another WD movie, Remember the Titans. I used both the default ipodTouch and the settings that maineman provided and all worked without audio sync issues.
PC2 is the newest WD movie we have. And Titans is the next in line.
So for now, my only issues are with PC2.
