Hmmmm....... apparently I'm wrong. It seems to be hard to find any info, but I've seen a few references to Apple including analog video on the Mini DisplayPort spec-- unlike the standard Displayport, which does not, and which is where my reasoning went awry. I just assumed that Mini DisplayPort was a miniaturize version of the full size spec, but apparently not. As you note, the fact that Apple makes a Mini DisplayPort to VGA adapter means the analog has to be in there somewhere (although if you read the reviews at the Apple Store there seems to be some problems, so the implementation might be flakey).
I'm actually a little surprised Apple went this route, since they don't usually worry to much about backward compatibility when it comes to connectors.
At any rate, you're still
on the hook for a converter box, since VGA video handles RGB and timing functions as separate entities, whereas composite and S video are looking for those things combined. And no, it doesn't work to just stick all the wires together inside an adapter shell, it has to be done electronically.
EDIT: I just saw that your TV supports component in. Depending on the video card and the display device, just a simple VGA to RGB on RCA cable might
work. You can get a six footer from Monoprice for like $6, so it might be worth it to give it a shot.
Failing that, you'll have to spend upwards of a hundred bucks to get something like this.
