Bug Description

Report from Don Mahurin:

I modified dvdbackup to avoid unused blocks according to pgc traversal.

For the source of the change and for details see:


It uses libdvdvm from libdvdnav. While libdvdvm is not exactly prepared to function as a stand alone library, it is sufficient for most cases.

I don't know the specific details of ARccOS, but this modification can avoid such intentional bad sectors.

By default, the behavior does not change.

Using '-r u' will calculate and skip unused blocks.

I've tried this version with a DVD which appears to have these sorts of blocks.
The copy in its entirety failed... let me know if more details are of interest.

I'm hitting this problem more and more often now. I also tried dvdbackupx, and it didn't work for me, but the idea sounds like the right approach.
