Dvd shrink help error

hello, i am trying to backup a burned dvd for a friend. when i do such i recieve this error, data error cyclic redundancy check. is this because i have already burned the movie and it wil not let me, how do i get around it if i can. also i have tried with dvd dycrypter and older version of shrink. please help.

hi. the problem occurs usually due to a scratched or damage disc - in other words your burner cannot read it. it should not have anything to do with it being a burnt disc. try cleaning it and try again with dvd decrypter.
