I really am not an expert on what is out there to use, but i don't want to spend more than $20. My goal is to record some call of duty gameplay and make some montages. I know MW3 already records, but i don't know how to get that recording onto my computer. So im looking to buy a cheap and simple device to make the xbox to computer transfer. Any help?
