I have a SA8300 HD box given to me by my cable company with all sorts of 'HD/DD' promises... Im in South America, and Im not sure really what can or does come through the cable into the box with respect to HD/DD.
But just in case, I have it connected via HDMI to the Plasma and via the Optical link to the Dolby Digital Processor.
On a few channels, the 'Dolby Digital/AC-3' green light lights up on the processor, just like it does when I play a DVD. However, I only hear audio through the 2 main front speakers. No central, no surround, not even on a movie channel which lights up the DD/Ac3 green light.
So my question is, am I receiving 5.1 or not? I called the company and they havent got a clue (honestly), so how can I tell?
Do HD/Digital channels transmit in real 5.1? i.e. you should hear voices on the central and surround sounds, etc
