Without starting a major discussion on benifits of one over the other, could someone lead me to a link that shows the difference between connections?

I have connectors that all end in RCA plugs. Some of the connectors have 3 plugs, some 2 and some only 1. Can I plug a red, white and yellow connector into a red, blue and green socket (component)? Can you use Analog audio connects for Component video?

How do I tell if the single plug connector is Coaxil?

The only ones I'm sure of are the s-video and the 75ohm antenna wire.

Thanks, Dale
