The CNBC HD channel is a waste, unless you want to see stock market figures in HD!
Re audio : The mtunes audio does not appear to be in stereo, leave alone 5.1.
Also, I have connected the HD set-top box to my receiver (Denon 1911), it doesn't appear to be in 5.1 surround sound.
When I connect my bd player to my avr, multi ch in signifies 5.1 surround and the avr recognises and displays dolby digital on its screen. No such thing happens with this hd box. There is an option under audio settings to choose dolby d or PCM in the box, but no effect on the sound . Ideas anyone?
