Read the fourth sticky post on this forum or click the Guides tab at the top of this page. It gives guides for both DVD Shrink and DVD Decrypter that should answer most if not all your questions. http://forums.afterdawn.com/thread_view.cfm/5540 I prefer to rip the ISO image with DVD Shrink to my hard drive first then write the ISO image to disk with DVD Decrypter later.
