Hi, I'm new here and I have a question about using DVD shrink to backup both Rocky and Back to the future. I have tried countless times to use DVD shrink for BTF every time I keep receiving disc read errors all over the place and as of yet been unable to use DVD shrink to backup this movie. Is there some kind of unknown copy protection which the dvd shrink program or any other program for that matter has that can't be broken? I've used many different dvd copying programs and no matter which one I use, every time I'm unsuccesful, I've also used Iso buster and virtual drives as well. Any help here would be appreciated, thanks!
