Hi James,

I know I should have, but it was just a quick thing I put together - red,
green and blue all get the same weight.  You can see in the photo that green
appears slightly darker and blue slightly lighter than in the RGB
screenshot.  I can try replacing the resistors and taking another photo of a
more accurate S-video conversion.
The circuit is dirt simple, just some resistors and a 3904 transistor.
