Wow, I can watch videos on up to *5* TVs simulatenously! What a technological marvel!
Oh sorry.... I meant to say "What an artificial limit". 
Shame the 360 wont support DivX/XVid ... Guess I will have to wait 6 months until its hacked. 
Other than that, Media Centre in the 360 is a great idea.
PS. When are we getting a video on TCM (Trusted Computing Group/Module/Platform) and how the corporations are going to lock down our access to media? Guess thats not quite the sort of feel-good press MS wants on channel 9.
