I have some dual layer DVDs I am trying to make backups of, but after I record the backups, some of these DVDs don't work correctly. The original discs have a message that plays before the main movie, then the movie starts. This is a black screen with white text: "The following interviews and commentaries are for entertainment only...". The message is repeated in French on the next screen, then the movie starts. When I made the backups, this screen is shown, then the French message, then it goes back to the same message and these screens continue to repeat instead of playing the movie. I'm using DVD Decrypter 3.1 and DVD Shrink 3.0 Beta 5 to make my backups. A couple of these DVDs include "Trapped" and "Identity". Does anyone know what I am doing wrong and how I can make new backup discs that work correctly?
