I guess I'm the next person late to the party ... I'm trying to backup my HD-DVD pile and having difficulty. Some rip fine, but many generate tons of "corrupt or invalid" errors. I assumed I was a victim of laser rot, but I just imaged a disc undecrypted, and it read fine. So it's starting to look like Make MKV doesn't like HD-DVD any more.

I ran the old DumpHD tool, and got a "key is revoked by drive" error. Might MakeMKV have the same problem? Anything I can do to help fix this problem?

Problem discs:

• Bourne Ultimatum
• all Harry Potter discs

Edit:300 is actually dead, it's one of those combo discs known to fail.
