Processing Key, Media Key and Volume ID found!!!

Wooow!

I think I just found the Volume ID of King Kong.

But I'm shocked! It doesn't appear to be anywhere near random as I expected it to be!! This could mean (just maybe) its guessable/computable...

If so then if we find the Media Key** we wouldn't have to use WinDVD to grab keys anymore . And the Media Key doesn't tell the AACS LA which software player was hacked so... This could also be the reason why AnyDVD supposedly can decrypt without the need for grabbing keys from WinDVD's memory which puzzled be deeply.

I don't want to get ahead of things but if this is true this could be very deadly for AACS. I wonder if this is due to some technical limitation. I will tell more later. Have to go to work now .

Oh yeah here it is:

Code:
    00000000: 00 22 00 00 40 00 09 18 20 06 08 41 00 20 20 20
    00000010: 20 20 00 00 xx xx xx xx xx xx xx xx xx xx xx xx
    00000020: xx xx xx xx
Look at Section: 4.10.3.1 Volume Identifier in Introduction and Common Cryptographic Elements for more details.

PS. For some reason (even though i'm pretty sure this is the volumeid) I just can't believe it. But it really seems like the id is split in two parts of 64 bit: one part only 00's and 20's while the other part is a little more "random" (which to some degree would make sense seeing its also split in half on the disc).

** Later in this thread it became clear we need a Processing Key. But it amounts to basicly the same thing.

Update: The Media Key of King Kong has been found now .
Update 2: The Processing Key has been found too .
