hi. a bit questions...

1 - i know that xbox arcade cant play old xbox games. I googled for it, and some people say dtahat we still can play old xbox game on xbox if we have the hard disk. Can someone confirm this?

2. Bought the webcam for xbox. Any of you guys have and really use it? i thought it was compatible with windows live messenger, but i was wrong ( i guess ). So, the webcam is only for xbox - xbox video chat is it? What else can the webcam do? cuz it was like rugi to spend money on it~

superb answer. thanks!!
