DVD Decrypter to DVDshrink, what am I doing wrong?

Rip the DVD to disk with DVD Decrypter in file mode, All Files (DVD Shrink needs a full disk to work on). Then open in shrink in File Mode (Ctrl-O). Make sure you are using the latest versions (DVD Decrypter 3.5.2.0 and DVD Shrink 3.2.0.15) This is by far the best way to backup a disk - especially with the new arCCos copy protection that DVD Shrink can't handle. I always burn with DVD Decrypter, but via PgcEdit - see for how and why. Good luck

link didn't work, arccos going to be on many dvds now? dvdshrink won't be updated to support it?

that sucks, hopefully he releases the source so someone can pick up the project?
