Well, that didn't work either. Before I call it a dud adapter, I'm going to test it on the PS3 and another device that uses those cables tomorrow and see if I can get anything from it. If not, then I'll call it and see about getting another one.
I don't normally work with these cables, but I figured it was a simple matter of matching colors up and what-not, which it is, so...I don't know. I know the PS2 works, because plugging it directly into a TV works fine, and I know the VGA ports on the monitors and the TV work because today I swapped them for DVI connections to my video card.
