I haven't opened up the project box to have a look at that board lately, but
I have a feeling the chips aren't available any more and that the board has
too many other components to make it worthwire to build as-is.
Stephen Fischer suggested a few chips a while back. This one in particular
is probably ideal:
It pretty much does everything to generate composite & svideo all by itself
and beyond adding a crystal to it, probably requires next to no additional
parts to build an RGB to S-video adapter out of it.
If we want simple and inexpensive, this is probably it.
