Double Image With Component Cable - WTF?

I just bought an Oppo 980 universal disc player, and took delivery yesterday. When I tried to connect it to my Sony television tonight with component cable, something very odd happened. When using component cable, instead of one image on the TV screen I get a double image - two identical, distorted side-by-side, 1/4 screen copies of the picture. And they're both in black and white. As I say, they each occupy about 1/4 of the screen, and are surrounded by black.
When I switch to S-Video, the image displays perfectly on my screen. So the disc player is evidently working properly.
When I swap out the component cables, and connect them to my other DVD player, it works fine - I get a perfect image. So it can't be the cables.
Disconnect them from my old DVD player, plug them back into the Oppo, double image in black and white again.
Some additional information - there seems to be some sort of tracking issue involved. The two double images occasionally lose "tracking lock" (I know that's not a real term; I just made it up because it seems to describe the problem pretty well) and suddenly distort very badly in a sharp diagonal orientation, if you understand what I mean by that. They twitch and jump, slanted very sharply from the lower right corner to the upper left, and then suddenly the tracking seems to "find" itself again, and the two double images recover themselves, and seem somewhat stable for a period of time. Then they go bonkers again.
This happens both with commercial discs and with homemade discs, if that matters at all.
So. The cables are fine, and they are connected properly. It's not the TV, because it displays fine when I plug the cables into my other DVD player, or when I connect the Oppo with an S-video cable. I cannot find any setting in the Oppo menu that seems relevant to this issue. Anyone ever heard of this before? I'm baffled. It seems vaguely familiar, as though I've heard of it somewhere before, but I can't recall any real details about it.

It is sending the s-video image to your component connection, which gives you a deinterlacing issue. Basically, an s-video image uses the scaler in the DVD player to send the deinterlaced image to your display, while the component used the scaler in your display/receiver to deinterlace the original interlaced image, thus two images.
A little more explanation......http://en.wikipedia.org/wiki/Deinterlacing
You can't switch cables when the player is turned on or the duplicate image (s-video) will be transmitted across the component cables.HT Optoma HD25 LV on 80" DIY Screen, Anthem MRX 300 Receiver, Pioneer Elite BDP 51FD Polk CS350LS, Polk SDA1C, Polk FX300, Polk RT55, Dual EBS Adire Shiva 320watt tuned to 17hz, ICs-DIY Twisted Prs, Speaker-Raymond Cable
