Well, the video capture card problem has been resolved.
I ended up going over to Frys yesterday and picked up a motherboard, cpu, and memory (2 motherboards, actually, more about that later).
The upgrade went smoothly … Linux adapted to the new hardware without a problem. Windows XP, however, wouldn’t even boot. I had to reinstall. I kind of expected that.
However, the capture card is seen by the PCI bus now, and is fully functional in XP. I need to figure out how to make it work in Linux though.
