It depends on which PVM you get. Mine doesn't support S-Video. It supports Composite and RGB.
The Genesis looks so much better with S-Video because the Composite video quality was HORRIBLE on most hardware revisions. Colors are dramatically different between Composite and RGB in my testing. Other systems don't have nearly as bad Composite Video output as the Genesis seems to have.
