I would like to know how to stream live video from my Xbox 360 to an online website.

There is a website called http://www.ustream.tv/ and that's what I mean...

There are people playing GTA IV, COD 4 and streaming it live. I'm not talking about using a video camera, but hardware such as a capture card, to produce 100% quality sound/video.


Anyone know of a tutorial or mind helping me?
