Russ,
I would point out that the VGA to RGB/H-V cable will work for RGB/H-V (5 cable inputs) but will not work with standard Component with only the red, green, and blue cable inputs. You must use those extra black and white cables to total 5 cables. Converting to the standard Component cables is not enough and will not work. I've tried it. Please let me know if you've been successful converting to only red, green, and blue cables.
The only way I've been successful converting to just the 3-cable standard component video is by using an external scaler, which yields less than favorable results.
