Full version of fraps? Hypercam?
If you have TV/cable interface with your hardware I think you can record from A/V out. I don't think it's changed, but I am talking from 10+ years ago when I was directing amateur local broadcasts live. We used a setup with computers (and a God awful system called trinity video editing). It required an interface with the computer hard ware for the technical directors and the clip recorder/player tech while I commanded it all. I'm sure there are interface cards and provisions you can buy.
