Nononono. No. As per the reviews, that is a cable designed specifically for video cards capable of outputting TV-out signals via the VGA port. This is such a highly specific application I do not even know of any video cards that are capable of such functionality.
A real VGA-to-S-Video/Composite looks like http://www.monoprice.com/products/pr...seq=1&format=2 .
I hear something like http://www.datapath.co.uk/products/video-capture-cards can capture VGA signals directly, but I also hear it's hella expensive.
