Connecting PC to old style projector

[Stanach]

I have a projector that only accepts bnc (coax) inputs. I have video cards with VGA, DVI, and tv-out (s-video and RCA). I had an S-video to BNC converter, but the projector's video output quality stunk. I tried connecting directly to a TV via RCA, and again, the video quality was almost unusable.
Because the card uses a splitter like cable to create the S-video and RCA ports from the single TV out port on the card, I'm wondering if that port, or splitter is bad.

What I'd like is a way of converting the DVI or VGA to a single BNC. Anyone have a suggestion? All of the converters I can find produce BNC-5 ends. I've just ordered a new (cheaper) card with an actual S-Video port on it, which will eliminate the need for the TV-Out to S-video/RCA converter, but in using it, I'm loosing the performance of my better card.

Thanks for any assistance.

Is anything on this page any use or is that what you mean by "BNC-5 ends"?

Those are exactly what I was refering to as BNC-5. While perfect for other applications (HD TV?), they simply arn't anything I can use.

any other ideas?

Thanks for the input!
