What would I need to purchase to copy encrypted dvd's on my Mac OS X? I believe, at least a couple of yrs., ago it was legal to copy one backup disk if I purchased the original. I've seen the Roxio software but it doesn't handle most dvd's because they are encrypted. I used to have a pc and I downloaded DVD Fab Platinum. It did it all. But I haven't seen anything like that for Macs.
