I have been trying to backup my Meet the Robinsons. I have used the latest versions of CloneDVD, AnyDVD, RipIt4Me, DVDShrink, and all are the same - no sound at all - whether I chose full backup or movie only. This has never happened with any other DVD. I have tried two different PCs and even a laptop - all the same. Just ripping the whole DVD, and just the movie, with AnyDVD still gets no sound. The DVD itself plays great. Help!
