I've got my Wii connected to my Onkyo 705 amp via Component. My amp is connected to my TV via HDMI. Why is my Wii outputting a 4:3 picture instead of a widescreen picture on my TV? I've set my Wii to 16:9 and 480p output. I've connected my 360 in the same way and it's fine. If all else fails I might have to go back to going direct to my TV with component.
