I have tried to connect the kids N64 using its own cable, which is a 3 plug phono connector. Yellow - Video, Red/White - Left/Right Audio. I Put the Yellow directly into the Pannys Composite but get no picture The same cable works just fine on thier TV & the Sony in the front room. Are there similar problems with X-Box or PS2s? I don't want to buy them something I can't blow up on the projector.
