Lucas destroys your Xbox

The new Star Wars bonus DVD erases elements of your Xbox's firmware without informing you or giving you a chance to decline. This is apparently deliberate, as part of an "anti-piracy" effort aimed at punishing people who play the Star Wars DVD bonus disk in a modded Xbox.

This information can be important for some people with older bioses (booting xboxdash.xbe), people using exploits or simply those who don't want their dash upgraded.
