Capturing PC Video On a PC

I’m looking to capture video from my PC (things I’m doing on screen, such as the action of a game) to play/edit on a PC (in, say, MPEG or Quicktime format). The only solution I can come up with so far is to plug my SVideo out on my video card into a VCR, record what I’m doing, then recapture the video from the VCR with a TV card. It seems like there HAS to be a way to keep it digital, though…

Here are some programs you can use to capture full-motion video from your screen in a variety of formats. Some are free/shareware, some with trial periods.
