Hi Big MaCanadian,
You seem to have the iBook AV Cable with a 3.5mm jack on the end, as required for 500mhz and 600mhz iBook G3 systems. This cable is not compatible with any other Apple product. You will need to get a mini-DVI to SVideo/Composite cable from Apple, in addition to a set of 3.5mm to RCA Stereo and composition/svideo cables.
It's a bit of a retrograde step in some ways, but it can do svideo, which is a better video standard, so there's some pluses too.
