I apologize for giving short answers.  Sometimes you get too close to a 
problem.

The NTSC ability of these cards is a bit strange.  The timings are all 
there and if you hack the cable you can get black and white images.  The 
sync is off the green.

In order to obtain the color display, which is there, you must go through 
a video conversion box.  This box takes the correct timings and adds the 
color burst.  There are external boxes and are available from third party 
developers.

Sorry if there was any confusion.
