Ah, sorry I forgot about that. I use WebCamMax which acts as a virtual webcam. You can have it "cam" full screen or just a portion of your desktop (or movies, pictures, etc). It even does picture-in-picture. It's a pretty nifty piece of software for what you are trying to accomplish. It is a couple dollars, but worth it. There may be something out there for free, but I dont bother getting into those programs.
