I had this same symptom once going from S-video out on the video card 
through a composite to S-video converter, and then through composite 
(RCA) cable to a TV.  It turns out the composite to S-video converter 
wasn't meant to work the other way, and near as I could tell, was 
dropping the chrominance (color) output from the S-video signal, and 
only passing through the brightness signal, resulting in a black and 
white picture.  I ended up using a different video card with a real 
composite TV-out jack to that particular TV, which restored my color 
picture.

Kind of a long shot in your case I know, but I thought you might be 
using a different cable in your old system where it works compared to 
your new system.
