Radeon RCA video pc card

The only Radeon model I found in stock on Newegg that includes composite output is this one:

Here are some searches that show other models with built-in support for composite output:

Alternatively, you could get a VGA to Composite converter box:

That way, you wouldn't be as limited in your choice of video card - many come with a DVI to VGA adapter if they lack the VGA port on the back, and they can be purchased separately for about $5.

Edit: Here's a list from AMD's website of their cards that have composite output:
