Recommended Recording Equipment for Xbox360/CRTtv to PC

I want to start sharing videos, but I do not know what kind of equipment is used to do this without having some kind of laptop to USB device with software recording gameplay live as I play it.

I was hoping someone could post here the common methods of sharing video recordings for replay sharing on youtube.

Also I have never uploaded anything to youtube, I am assuming its simple, but if it isn’t feel free to share that as well.

Thanks in advance
