I've run into "almost" the same thing as of late. ISO image plays fine. Burned DVD's start at end credits, mid movie or elsewhwere, whether on the computer or in the standalone player (though both WinDVD and the standalone DVD player indicate they are starting at chapter 1). Have been able (after much experimentation) to resolve thus far by opening the image in DVD Shrink and having it create an ISO (from the first uncompressed ISO that was originally created with DVDFAB HD Decryptor) and burn with DVD Decrypter (rather than Nero). Have recently changed from Nero 6 to Nero 8 but am not sure if that's truly when the issue reared it's ugly head. I first thought it was another copy protection method but am really beginning to place the blame on Nero (8) or some screwed up settings within Nero.
