I am aware of the three types of DVD-Copy protection, CSS, Macrovision and Region Coding. Now I have been doing a bit of backup work using my new superdrive and the program DVD Backup 1.3. So far so good, no problems with about six or seven different DVD's. Yet I tried to copy a BBC DVD over, and several of the .VOB's couldn't be decrypted. Namely the copyright warning at the begining and about three of the large 1024 GB files. Is this a flaw in DVD Backup, or the DVD itself, or is their possibly more intense CSS encoding that DVD Backup can't get through? If so, does anyone have any ideas for other Mac OS X related software that can get through this different encoding? Thanks all.
