Composite and component are quite different things! Indeed they can both
be transmitted using the same type of leads (Phono's)

Right, I see. I'll have to get some component phonos then.

The SD210 doesn't output 'component' - therefore you won't be able to
connect it to the component in on the TV. The DVD has a S-Video output so
this would be the next best option for quality. (Presuming the TV can
accept S-Video)

Well, my SD210EB doees! I'm looking at the owner's manual now. Under
"connecting to a TV using the component video jacks". Y video out, PB Video
out and PR video out. They're there on the back of my player, too.

Just to confuse matters, SCART can carry RGB, S-Video and composite
signals. A RGB-SCART switch box could be another option?

Yes, a switch box might be in order.

Thanks for your help.
