I gave up on
DVD Shrink a while back and DVD Decrypter just doesn't cut it for me anymore. With the protection on a lot of the new movies available, these two are obselete.
I thought DVD Decrypter would be up to the task but it inserts "Dummy Sectors" and some of the movies do not begin until 5,6,7,8 minutes into the disc when re-authored with DVD Shrink.
My choice is
AnyDVD/
CloneDVD2, it always come through when DVD Shrink and DVD Decrypter fails, just as it did with two of the three movies I backed up last night.
