I have a strange cord that has a male 3.5mm headphone jack on one side, and some component video and audio outputs on the other. When I plug the headphone side into my computer, and the other side into my TV, I get audio across the cable, but no video. How can I send some video over the headphone jack in OS X? I know you can, because this cable is actually for a Beyblade toy and it somehow transferred video over this cable.
I think I found some more information (from Wikipedia):
A four conductor version (of a 3.5mm headphone jack) is becoming a de facto standard output connector for compact camcorders, providing stereo sound plus a video signal.
So how can I do this on Mac?
