Just thought I'd let you all know, my previously installed TV tuner card worked as a video capture device. I simply connected the VCR by coax cable to the TV card, opened the program I use to watch TV, pushed play on the VCR, and there it was. The card I have in case anyone is interested is the Pinnacle PCTV HD PCI card, and I'm using the TV Center Pro software that came with it.
Thanks for all the suggestions!
