where to buy a BNC to RCA component cable?

I have a Muse DVD player and it has BNC component connectors on the back but my Panasonic TV has RCA component connectors.

Where can I buy a set of component cables with BNC and RCA?

I finally bought some BNC to RCA adaptors from Radio Shack and tried component cables and there is indeed a step up from S video but I would like and all in one cable with out the adaptors.

thanks
