Unknown Error Message

Can anyone help me? I use DVD Shrink to compress my DVD’s and then Nero to burn them but for some reason I have been getting the same error message a lot recently, more with newer movies than older ones but it says “Cyclic Redundancy Check” and will not let me continue with DVD Shrink. Does anyone know how I can get around that error message?

Use a program such as AnyDvd, Ripit4me, and DVDFabDecrypter to bypass the copyright protections on the discs. Shrink is old and outdated and cannot handle them.
