How much you willing to spend? The main good ones are the Hauppauge HD PVR, Elgato and Roxio. But if you have less to spend, you probably get less qualify

do NOT get a roxio, the quality is terrible, pvr or preferably avermedia, both of those are good. elgato, ive never seen, but you can look it up on youtube.

Roughly I'm looking to spend £35 and probably not much more, but I just don't know what to get exactly, and to get it in a decent-ish quality for the price. :)
