I have a backup of the movie "Heat". When I backed it up, it backed up fine; I used my usual process (DVDShrink then burn with Nero). But I recently tried to copy my backup, and I receive errors with all software that I use. I have tried DVDShrink, Nero (just using the copy DVD feature), and DVDFab Platinum. With all these programs, the copy process stops around 58%. It just starts going very slow and has read errors. Anyone know why this would happen? It doesn't really make sense because I figured with the copy, all the protection has been removed.
