You can pick up USB tuners for under 20 GBP now.  I doubt internal PCI ones 
are much more for basic functionality.

FRAPS is pretty much the standard for 3D content (games, 3D software, the 
Vista desktop!) and IME works well so long as you have enough CPU power 
spare to stream the video to disk - I think it lightly compresses it 
(losslessly IIRC) before writing, but you certainly want to recompress it 
later to a standard format that takes less space.

Given that my fairly recent PC can compress a 1920x1080 signal to h264 about 
4x slower than realtime, I suspect you are talking about some serious 
broadcast-quality kit to do that job at desktop resolutions and frame rates.

Of course you could output to sVideo and then feed that in to a bog-standard 
analogue capture card if you're not worried about the quality.  Or just 
point a video camera at the monitor :-)
