Composite is the most basic. It has the entire signal in one cable. The connection is generally RCA type. S Video separates the Y & C components of the video. For sources where this separation is native (originally recorded as separate signals), this can deliver a significantly better picture. If it is not native it varies--sometimes the composite is better, sometimes the S-video is better. The component is used on most DVDs, although your TV if it's more than 3 or 4 years old, probably does not have a component video in. This is really 3 composite video cables. They carry separate Y, Pb, and Pr signals.
In general, if you have component available to you on both your TV and DVD player, this will yield the best results. S-video would be the second choice, followed by Composite as the last choice in terms of best picture quality.
Hope that helps.
