Excerpt: "The latest attack vector bypasses the encryption performed
by the Device Keys -- the same keys that were revoked by the WinDVD
update -- and the so-called 'Host Private Key,' which as yet has not
been found. This was accomplished by de-soldering the HD DVD drive's
firmware chip, reading its contents, and then patching it. Once that
was done, the firmware was soldered back onto the drive."
