Except it IS an s-video connector. I can plug an s-video cable directly
into it, and it displays just fine. It is modified in that it has extra
pins to provide extra capability to a breakout cable. Both component
capable nVidia cards I have owned operate this way, as well as another
three at work.
My old ATI AIW had a 9-pin connector, but s-video was still one of the
formats supported on the breakout cable.
