I know this is probably easier than I'm making it out to be but I swear I'm missing something. I would like to be able to record some of my play-through for games on my Xbox 360, maybe even stream it live if possible (maybe). I don't want to get a camera and just record off the screen, that looks terrible. So here's my set up. I have a 1080i HDTV, my Xbox, PC, and PS3 are all hooked up to it. Its just a manner of switching channels. I'm pretty sure my PC doesn't have a video caption card, but it does have some interesting RGB ports to take advantage of that. Would I have to get video caption card, and any special switchers to be able to do this?
