VGA (a form of RGB) will give you the best picture. S-Video separates the luminance (brightness) from the chrominance (color) portions of the video signal. Component further separates the signal into luminance and two luminance-color differential signals, this gives better color rendition. VGA or RGB separates the luminance information for each color onto its own signal line and thus offers the best resolution and color fidelity. The differences as you move up the scale from composite to S-video, to component, to RGB get smaller. Component and RGB are not dramatically different, but RGB is better.
