Hi Everyone:

        I wish to make a backup copy of a family movie DVD using DVD Shrink in conjunction with Nero.  Unfortunately, I am running into the following error which has become an obstacle to backing our copy up:  Data Error: Cycle Redundancy.  

        Any help on resolving this issue will greatly be appreciated.

       Thank you.

A "CRC" error is most often caused by bad media - it could be any of the following:

1. A dirty disc,
2. A scratched disc
3. A poor quality disc (cheap media if it happens during the "Burn" section of your work)
4. A bad disc from the Mfgr.

It can also be from a bad optical component in your drive. At this time I don't believe it's your drive at all.

HI

      We were able to take this same DVD and play in within the entertainment center with the DVD player just fine.  If it had bad sectors on it, would there had been problems with the playback of this DVD?

       Thanks

DVD Players are magnificent beasts. they are absolutely forgiving.. and minor errors will be skipped without necessarily losing any visual information (25 frames per second, you won't notice).  Computers are less so.  However, it could be possible the CRC errors are due to Nero having a habit of not ejecting and flushing the disc buffer before doing validation.  DVDDecrypter (no longer legal) which DVDShrink has an option to write with, ejects the disc first after writing just to make sure all's clean before reloading it fresh.

Hi There:

       Thank you so much for your followups.  After carefully going through the resourceful and insightful link supplied within your beginning response, I decided to give DVD Decrypter and CloneDVD a try.  Currently, I am using DVD Shrink and Nero for my DVD backup needs.  
I think it is time to branch out more and give other ripping software titles a chance.

      Thanks again for your guidance.
