High End Video Capture?

A reader asks: "I work for a very well known company specializing in Game Engine Middleware. Recently we've been trying to gather together marketing material for some new products, and one step towards that end is capturing high resolution gameplay footage (1280x1024) into some kind of movie file for editing. According to the 'experts', the best solution is to scan convert the DVI out into HDTV 1080p, and then HD capture it back into another PC for editing. Surely all this conversion to 'broadcast' quality is pointless - has anyone come across a pure DVI capture solution?"

There are many other alternatives to this. This is just one suggestion that I have tested to work.

For my capture PC:

Opteron 254 (2.8ghz)
Tyan Thunder K8WE
Adaptec PCI-X Ultra 320 SCSI Raid controller (39320 series)
4 x 300GB 10,000rpm Seagate SCSI disks running as raid0 (6-8 would be best)
New Nvidia graphics card
2GB ECC RAM
