    i.e. this thing:

    I'm a bit confused because the current configuration I have right now (which just broke) requires me to go from mini-DV to VGA... then VGA to this little magic box which must be plugged in to convert the signal or something of the sorts and then it goes to TV out.

    Basically, I my question is, why does the apple adapter not required to be plugged in?

    You don't need a D/A converter if the computer is outputting the proper signal.

    The only reason your box needs to be plugged in is because it takes a dumb source and converts it using an onboard chip, which needs to be powered somehow. The Apple adapter does not need to do this, because it's an adapter and not a converter.
