That is the key for every HD-DVD disc on the planet. You see, the movie industry doesn't trust you to act like an adult with your own property, so they decided to lock it all up and only give the key to people that paid them enough.
The reason they can do this is because of an odious little law called the Digital Millenium Copyright Act. The DMCA makes it illegal to circumvent copy protection, even if that protection infringes on your fair use of your own property. I'm not a big fan of that, and I'm sure you wouldn't be either if you knew more about it.
