I can't get audio and video from blu-ray or DVD to TV from Reciever. TV is Samsung LN46A650 LCD flat screen, receiver is Pioneer VSX-1018AH-K. Blu-Ray is hooked to receiver via HDMI. Receiver is hooked to TV via HDMI, and optical digital cable. When I play the blu-ray, I get nothing on the TV. I've double/triple checked connections, but obviously I have something wrong. I've read the set-up specs on both till my eyes are crossed. What am I missing?
