Bad sectors in the first cell are typical of ARccOS. Open the files from DVDDecrypter with DVDShrink -> Reauthor -> Drag main movie title over to the left pane -> Hit "Set start/end frames" -> For start frame, go to chapter two and reverse to one second -> Hit "Okay" -> Hit "Backup". That should fix the problem, good luck.

The other option is to create a PSL file so DVDDecrypter knows where to insert dummy sectors.
