I want to route my HD E1 through my Pio reciever. I have connected it via HDMI and all i get is black. I have Firmware 2.2. My Reciever works switching between PS3 and Sky HD connected up to my PDP 427XD. I am completely Stumped.... I can connect it straight to the PDP and it works. I have also simply swapped the leads round for both the Sky HD and Ps3 knowing that these work and it still doesn't work. what coukd be the problem? What have i not checked?
