Capture 360 gameplay

Can anyone recommend a good and reliable software, capture card, or anything else I need to capture gameplay from my 360 so I can edit it on my computer? Preferably HDMI, been looking online  haven't had much luck. Thanks 

That's something I wouldn't mind doing. I wouldn't know where to start though.

Theres Hauppauge gaming edition version 2 this has hdmi cables or try a roxio capure card. For software many use sony vegas pro 10

HDPVR i heard was good.
