I have conquered the task of backing up a DVD that I own and burning it to a DVD-R. Great. But it is not readable on the two Commercial DVD players I have. Anyone know why? Equipment and Software used: Mac G4/OS 10.2 LaCie A05 external Burner Ripped with DVDbackup Compressed with DVD2oneX (if over 4.3G's) Burned with Roxio Toast Titanium Commercial DVD players: Yamaha DV-C6660 Sanyo DWM-390 Another way to as- "Does software exist (free or otherwise) for the Mac that Rips, Compresses and Burns DVD-R's that Commercial DVD players can read. Thanks! Jason
