I realise you’ve solved this issue, but should the region play that much of a part in the function of these applications? I do much the same of backing up the DVD so that my 3yr old plays it from a PC on the backup rather than the original. Small hands can’t help but mis-handle the disks. Using the above AnyDVD & Clone DVD versions I had absolutely no problems at all with both discs. Just to confirm this I did it on both PCs to be sure. Disc specs below from AnyDVD:

I think you have a problem in any of these areas:
- Disc is contaminated/damaged, but as you’ve said the same issue with other disc.
- Conflict of applications installed on the PC. Try to reduce the number of applications active in windows services that may be enabled to access the drive. If you have the time & HDD space, use a fresh install of windows with Anydvd & CloneDVD on their own to test theory.
- Has the DVD burner been giving erroneous results for other situations? It could simply be the pattern of work by this disc sets off a problem with the drive hardware. I experienced a similar issue with an older CD burner. A friend had the same experience on a single disc with their DVD burner until it died outright.
Good Luck!
