s video cable

Cables equipped with RCA-type connectors can be either better or worse than S-video cables. The triple set of RCAs in a component video cable will give the best picture, if your player or receiver can use it. The single RCA connector of a composite video cable is the least expensive and the poorest performing.

From worst to best:
Composite(single yellow RCA)
S-Video
Component(red, blue and green RCA)
DVI
HDMI

S-Video Divides the Chroma and Lumance. It provides a
MUCH better picture than Composite(Yellow video cable).
However, IF recording onto a DVD recorder, use the
yellow cable into the DVD recorder. The prosessor
in the recorder will make the picture BETTER than if
you went in with S-Video.
