@ Davidstjohn3,

Perchance when you are attempting to re-copy your back up copy do you have AnyDVD running? If so disable AnyDVD because it is not needed because all copy prtotection have already been removed in the back copy.

Most reasons folks cannot re-copy a back up copy is because the back up copy contains errors. Suggest using Nero CD-DVD Speed (http://www.cdspeed2000.com/files/NeroCDSpeed_408.zip) and check your back up copy for errors by running a ScanDisc surface scan. A correctly recorded back up copy should not contain any errors. If Nero CD-DVD Speed reveals errors these errors are most likely the reason you are unable to re-record your back up copy. Just because a back up copy plays in some DVD playback devices does not mean the back up copy is error free. Most errors are caused by the use of poor quality DVD media.

Best Regards,
