Screenshots can be captured via the developer page. If you're getting tearing in the screenshot, break into the debugger before taking it, so the screen doesn't refresh mid-screenshot. For video, there are no "cheap" options that I'm aware of. I've used a Slingbox in the past. Now I use an Elgato HD Game Capture.
