They only work with later-model ATI cards (not even the Radeon 7200s and
7000s I have kicking around).  Their newer GPUs are most likely creating
component video directly and sending it out the VGA or DVI-I port instead of
RGB video.  The cheap VGA-to-component and DVI-to-component adapters, I'm
guessing, are little more than a handful of connectors wired together.
