    How about this guy for converting RBG to S-Video?

    It's for old video games, but, IIRC they're about the same 15khz etc.
It does take 'composite sync' and we have it separate, but, 2 high speed
diodes should take care of that. Also has "RGB input level controls -
For matching RGB input levels to video game boards 
with high outputs."
