I have connected directly to this TV with HDMI. Video worked fine. Not sure if audio worked because I don't have any speakers connected to the Pioneer TV (everything goes through Onkyo receiver). I've tried plugging into the blu ray port - still no luck. I tried hooking up my neighbor's xbox through the receiver. It didn't work. I actually have 2 of the same Onkyo receivers. I tried through the other Onkyo receiver - no audio/video.
Is there any reason the xbox wouldn't work through the receiver, but I have no problems hooking up blu ray players, etc in the same manner? I really need to run it through the receiver because I don't have speakers hooked up to this TV. HDMI should pass video and audio from xbox to the receiver and then to the TV right? Thanks for any help!!!
