I have noticed that some people have had trouble backing up movies from Universal like The Bourne Supremacy with DVD Shrink. I did not have that problem at the time that movie came out or any other Universal movie. Recently I had upgraded my DVD shrink to version 18.104.22.168, the latest one. Now when DVD Shrink starts the Encode process, it errors or the program drops out when backing up those Universal movies like The Bourne Supremacy, Shaun of the Dead, Friday Night Lights, and also Ray. These movies were ripped using the latest version of DVD Decrypter. For those who want to compress these movies with DVD Shrink and are experiencing this problem try uninstalling the latest version and installing an older one. Version 3.1.7 seemed to work fine for me. Let us know if this does the trick.
