How can I send xbox 360 av (audio and video) to my pc monitor

Sorry I accidently put this in a wrong thread this is my second thread and I think I got it right this time. Could someone please help me. All I want to do is start recording my xbox 360 gameplay and make it into a movie. I don't really want something like a dvd recorder(I don't want to spend a lot of money), but I was thinking something that can send the av from my tv to my pc monitor, so I can record it from there. If I have to send it directly to my computer from my xbox 360 and not my tv, could someone tell me a way that I could split the signal because I like to play my games on my tv. Thank you

 

Basically any capture card can do this as long as your TV has video out capability. The ATI AIW aren't cheap but you can also use the video card for gaming so it isn't such a bad deal.
