I am trying to make a backup of my Little Black book. Columbia tri-star DVD. When I go to load it in DVDShrink 220.127.116.11 I get an error "cyclic redundancy check" The CD is new and no scratches is on it. I loaded it in DVD decryptor to rip files still get the same error in that. I even tried ripping just the movie files. Seems to be getting hung up on the first movie VOB file. The DVD has widescreen and full screen. I tried ripping both movie files seprate. Still got the error when it got to the first VOB file on both movie formats. I have no problems backing up any of my other movies. I backed 1 up after I tried this DVD and that backup worked fine. Anyone have any ideas?
