BNC to RCA

Hi,
I have gone to Radio Shack and other shops, but no one seems to have a clue what I am asking. I have video processor (Cal Labs) that has 5 BNC outs. My projector has 5 RCA ins. Now, the cable I have is BNC to BNC, does anyone make an adaptor to go from BNC to MALE RCA?

Please help? Until I have one BUILT to specs, I would like to buy an inexpensive adapter (radio shack quality would be fine) but can't locate one????

Am I looking for something that does exsist?
