THE MPAA is trying to ban the fairly public HD-DVD processing key from the internet. That would be the number 09 f9 11 02 9d 74 e3 5b d8 41 56 c5 63 56 88 c0 that has helped me in mashing up DVD content. The hex number also appears in song lyrics, on coffee mugs and on t-shirts. The MPAA is trying to suppress the dissemination of this number, which is causing a Streisand effect. The number was mistakingly published on the internet by the Advanced Access Content System. If lawyers needed any reminding, sending a cease and desist letter under the Digital Millennium Copyright Act often guarantees an eternal flame to the material in question. But we knew that already.
