I used to use dvd shrink and dvd decrypter. With Verbatim dvd-r's and sony dvd-r's burning at 4x and i never had a problem every backup runs great. So i figured since i was going to be backing up dvds for awhile i figured i would buy anydvd and clonedvd. Backed up a few dvds with it movies like four brothers and brothers grimm. The movie has slow points and sometimes it looks like the frams are going to slow. I set clone dvd to burn at 4x. I have no idea what i'm doing wrong. Is it better if i go back to dvd shrink and dvd decrypter?
