360 DVD hot-swap?
Somebody named Sharker posted a video on YouTube of a guy booting up PGR3 in a caseless Xbox 360, then "hot-swapping" it for a DVD-RW containing a ripped game. He literally pops out the spinning disc and swaps it for another (and not without sleight of hand flair). Presumably, this is a crude way to by pass the boot system and play those...uh...back-up discs some people keep for insurance purposes. Not sure about the legitimacy of this video or this technique. It's been up there since December, so I'm sure more has been written about it, but a quick search of various hacking sites didn't turn up anything. In any case, I wouldn't recommend trying it at home just yet.

Update: According to MaxConsole, this is a "silly old fake video." Proof of real back-up hacks to follow.
