there is a "workaround" for this, where you would split the RGB 
connector into three cinch connectors and switch these through your YUV 
inputs on the AMP. You would also have to switch the Sync through 
Composite to get a working setup.

There are some explanations and schematics for this out there on the 
web, but I don't remember where :-(
