I just bought the godfather trylogy and i am trying to back it up.
When i use dvd decrypter it says
1) That the slower method bruthjal force or something like that will be used instead.
Then it says that it cant open the protection of 2 of the files and offers me to use a key that used with another file or something like that (sorry for my english btw)
When it finishes, i use dvdshrink to compress the movie to 4.7 gigas but when it tries to read the files that used another key in decrypter it says that it cant be done cause of the protection.

Please try to help me, any ideas? Which one is the best solution or program to back the movie up

Once again thanks a lot for your help
