Having gone thru my Blade Runner box set completely now by ripping all the discs to PC, I found the following:
Disc 1 HD-DVD The Final Cut: No errors. I backed it-up to Blu-ray format
Disc 2 DVD only Dangerous Days: Errors. Unable to back it-up as a result but at least I watched the majority of it
Disc 3 HD-DVD Three prior versions: No errors. I backed it-up to computer HDD
Disc 4 DVD only Enhancement Archive: No errors. Backed it-up to DVD
Disc 5 HD-DVD Workprint: Errors. Unable to back it up as a result
I have not had big problems with my white ring discs to this point and so it is a disappointment to learn I too have "the problem". I do wonder if the issues are related to the obvious out-gassing of the disc cases i.e. my discs are oddly fogged too and while I can clean Much of the fogginess out, the errored discs can't be completely resurrected.
The Criterion rot issue made me be more alert to my HD-DVD collection, I knew previously that my Planet Earth HD-DVDs had problems playing in some sections that before were playable so I looked at the discs and they all had milky blotches on them that seemed under the surface. Is that the typical look of this HD-DVD rotting problem?
Also is there any current company redress to this issue?
