Whenever I make backup copies of DVDs, sometimes they wont rewind, the main menu is screwed up and is like half the title menu and half subtitle menu (i use nero v. 5.5.5.1)..... its weird, i was just wondering if anyone could shed any light on how to remedy that for me. Also, when your making a backup copy and all you want is the movie, can you tell me what are the essential files i need to put on the dvd to make it work, id appreciate it if anyone could answer these questions for me....thanks.
