Gonk you are the man and now my sons hero. I had my Xbox on video 2 and optical. I didnt know that the inputs were in an order when it comes to analog. That is interesting must be why you cant pick analog 1,2,x.

Anyway CP1966 if you follow Gonks instructions it will work. My config is as follows:

Input #3
Audio: analog
Video: Comp 1

Works like the 480 low res dream that the Wii is.
