You're not actually getting any more data on screen.  Your video card is
scaling whatever video mode you throw at it down to 480 lines, interlaced. 
That is all that S-video supports.  (Horizontal resolution is more than
likely getting squished down to either 640 or 720.)

For composite and S-video, they aren't.  They're outside the NTSC spec.  HD
requires component, RGB (VGA), or DVI/HDMI to connect between the source and
the display.
