I am toying with the idea of re-ripping my DVD at a higher quality than my current divx collection, for an eventual Apple TV purchase, but after a test batch of 10 discs, 2 of them wouldn't work. With errors indicating the disc was encrypted.
One was a Disney (or Pixar) disc, I think Ratattouie and another was LOTR:Fellowship.

DVD Decrypter breaks an incredible number of encryptions. Though I acknowledge that Disney has been getting VERY good at encrypting their DVD's. I could not decrypt WALL-E without assistance from the trial version of SlySoft DVDRipper.
The WALL-E DVD had somehow managed to convince the DVD Decrypter software that there were 50+ versions of the movie on the DVD, which is naturally impossible. All but one of those tracks were garbage, but using DVD Decrypter to determine which one was the right one was too difficult. Each track was only seconds different in length from its neighbours. Using SlySoft DVDRipper as a support tool, the garbage tracks were removed and the right track discovered.
Lately I've noticed an encryption method whereby cells of garbage data are placed at the beginning and end of the movie tracks proper, preceding opening credits and succeeeding ending credits. These cells of garbage data confuse the software into running read loops instead of progressing further into the movie for decryption. Fortunately, these cells are easy to spot as they are usually less than a megabyte in size and fractions of a second in length. Directing the software to bypass cells of irregular size and time duration
resulted in a successful decryption.
Honestly, the best digital lock I've ever encountered using the DVD decrypter software was on the Matrix DVD. The scenes where the filmmakers used the 360 degree camera tricks for the slow motion are not part of the movie proper, so in the movie opening when Trinity is cornered by the police, the scene where she jumps into the air and kicks the cop in the chest is missing entirely from the decrypted file. The soundtrack keeps on playing as if it was there though, so what you end up with is a sudden 5 second audio/video synchronization failure. No one's dialogue syncs with the movement of their lips for the rest of the movie.
