It seems that BackupHDDVD tool is working. There is now even a list of Volume Unique Keys for some of HD DVD movies in Doom9 Forum. The keys can be found by looking in the memory of Intervideo's WinDVD. The HD-DVD camp really seems to have a big problem. The compromised WinDVD versions will probably be withdrawn. There is also rumours that Power DVD would be compromised too. This is getting interesting. BackupBlu-ray tool coming soon?

I guess it's time to start a new thread with these since they have been officially found and tested * WORKING * perfectly.

Here are the Volume Unique Keys (Mostly USA) for the following movies:
...=12 Monkeys
...=Aeon Flux
...=Apollo 13
...=Batman Begins
...=Casino
...=Chronicles of Riddick
...=Constantine
...=Enter the Dragon
...=Equilibrium (Jap)
etc
