DVD Decrypter / scratched movie dvd and backup?

In short,

I have a few dvd movies which has been scratched to such a degree that DVD Decrypter can not transfere them to the HDD. It stops and report an I/O error ! :a
The movies can be played back alright on the PC and in a stand alone DVD player: Therefore, I asume that the error is not critical.
Is there any way (a program maybe ?) where I can change the ‘read’ tolerance in this transfere proces to the HDD to such a level that the transfer can happen anyway ?

I use this NEC 3500A which otherwise is an excelent backup’er.

Any other suggestions will be appreciated :iagree:
