CarlJohn,
You mention an s-video adaptor...
if you are using a vga to s-video adaptor/converter, you may want to make sure the unit is working correctly... I had a Radio Shack unit that was bad when I purchased it, and spent an unfruitful couple of hours trying to make it work... returning it to the store, (they only had 1, and it was a resealed box), and getting a refund... then purchasing a cheaper unit online that works perfectly, and easier to setup... Radio Shack for emergencies only, since then!
