I have a series of a 21 disk (no copy protecton issue) series. When I first got them, I made a back up of all 21 disks w/no problems. Since that time, I have made more copies and each time I make them, I get progressively more errors.

I was under the impression that since they are digital, digital copies would be an exact duplicate of my "original" as opposed to the degradation which comes from copies of copies of copies or VHS or such. And all my secondary copies have been off my original copy.

At first, it was one error on one disk only but getting into the next few copies, I got more errors on more dksis. Mostly the errors relate to something like "cycle redundency" or such. Also, I have checked and they are clean and with almost no scratches other than normal handling which do not appear to be anywhere near "bad."

Any ideas of what would cause this degredation over several times copying?

Thanks
