All my burning seems to be going well, thank you Scuba Pete, but it seems about one out of every three backups won't play. I don't get any errors while using dvd shrink and decrypter and it says operation successful but then the DVD won't play in either a stand-alone or my pc's dvd player. Using TDK plus R media, with an HP burner, and running windows XP. The movies that haven't burned aren't particulary new ones they are, Harry Potter, Walking across Egypt and Godsend. Any suggestions would be appreciated. Thanks very much.
