unplug the yellow video cable that's going into the card, and plug it into a monitor to make sure the picture has color. if so, the card or drivers are bad. if the picture still doesn't have color, then i would ask if you're using an s-vhs vcr, that has an s-video output, and an adaptor to convert s-video to composite video (the yellow rca cable). in s-video, one of the wire pairs is for luminance, and the other for chrominance (color). if the chrominance pair is broken somewhere along the way, all you'll get is a black and white picture.
