Used for broadcasts in surround if you don't use
a cable box. I think the manual explains this.
I just purchased a PN50A650 and a BD-P1500. I have a Dennon receiver and it has been working prefectly with a digital optical cable. I have it set to Auto so that it sees the best audio signal coming into it. So I run the BD-P1500 to the PN50A650 via HDMI cable and then run an optical cable from the TV to the receiver. When I run the optical cable from the TV to the Receiver it only renders Dolby Pro Logic II but when I run the optical cable from the BC-P1500 to the receiver, it plays in Dobly Digital/DTS/THX and so on...
So my question is does the PN50A650 allow for digital 5.1 pass through or does it automatically convert it to 2.0? If it converts to 2.0, what's the point of having the optical output on the TV? If there is a setting that I have missed to allow it to pass the digital 5.1 sound, please help me locate it.
