Really struggling to get Dolby 5.1 with my new combination. I have the newest Motorola/comcast box with an HDMI cable going directly to my Pioneer PDP5080, and an optical cable from the TV to the optical input on my JVC RX-884 receiver. Cannot find a combination to get dolby 5.1 to save my life. Any suggestions?
John S is correct the digital out on the TV is used only if you have a roof antena hooked up to the TV as your source. If you are using a cable box use the digital out on the cable box to the receiver.
