I have some DVD's that I burned backups of using Mac-the-Ripper & DVD2ONEx. They used to play back on Front Row & DVD player but now they don't. I get an error message looking for Copy protection encoding. Obviously it cannot find any. Is this an update in 10.4.5, 6 or 7? It must be since Apple wants to sell Movies now through ITMS! They still play back on a regular DVD player, though!
