I don't know that card. Probably you can find suitable cards via Google etc.
Those cards also have features like genlock.

When you convert to composite video (RCA), the results will not be much better. The only advantage will be that you skip a hard-to-control scaling step. The VGA output still can be controlled with specially tweaked modelines, while the TV-OUT cannot.
Of course you will have best results when not converting to composite but keeping the signal as RGB or YPbPr.
But it depends what kind of broadcast standard you are using too (analog or DVB).
