Okay, I'd better explain this further, but these suggestions are definitely helping.
I've got a Wii hooked up via component to my TV, and the receiver hooked up to the TV via basic AV. I (finally) figured out how to get sound, but I guess my main question is how to hook up the Wii to the receiver through component, and be able to play it through the receiver instead of the TV. My main problem is as soon as I do that, the TV does not recognize that anything is hooked up to it at all...I get no picture whatsoever, no sound, it's like I don't even have the system.
I saw that MDS said "Typically you'd run audio and video from each device to the receiver and then use a single video connection to the TV." So, right now since I'm using the regular white and red cables from the receiver to the TV, I need to hook the component cables from my Wii to the receiver, in addition to the white and red cables?
Sorry if this isn't making any sense, but I really really appreciate everyone's patience.
EDIT: Okay, I've got the Wii hooked up to the receiver now, but still no picture. I'm starting to think that I'm missing a cable from the receiver to the TV in order to get picture, because all I've got is just the red white, and yellow cables hooked into the TV (AV out) from the receiver.
