I wasn't sure if you really needed this answered, but I'll state it here in
case others don't know.  S-video just separates the intensity from the
color signals (much like how TV is broadcast), using two pairs of wires.
Composite just combines both signals into a single pair of wires.  The
reason for separation is that the intensity (luminance) signal contains
more information (bandwidth) and that the color (chrominance) signal
overlaps some of this signal, therefore if the signals are physically
separated, the luminance signal will be cleaner.  At least, that's the
theory.
