How to record the screen in Battlefield 3 on a PS3?

Does anyone know How to record the screen in Battlefield 3 on a PS3?? (if it is possible)|||there's no theater mode, so you would have to buy a PVR or use a camera|||You need a capture card or a VCR (but don't use a VCR), and you need to hook it up to your computer to capture it. If you have money and don't mind spending 250 of it, I recommend the Hauppauge HD PVR, and if not, Dazzle. PLEASE, do not get a camera and point it at the screen if you plan on putting this on YouTube.
