I just got digital cable, and hooked up the digital out from my cable box to the coaxial2 input on my 950, which is assigned to Video 1 (I have S-video, composite video, right and left analog audio connected to Video 1). If I go to a channel that has dolby 2.0 or 3/2.1 I get sound and can use the digital audio feed with the assorted surround modes.

If I go to a channel that is sending a PCM stream, I get no sound, and if I try and change the surround mode I see "S/PDIF unlock" on the right side of the display. Page 31 of the manual shows how to lock a data format. So I attempted to unlock the Video 1 input, but it was already set to Auto, so this is not the problem.

If I switch the input to analog, I see PCM 48k and can process that signal, but this can't be the way this is supposed to be handled. By the way, I'm doing this with NY channel 7 and HBO via Cablevision.

Any ideas?
Thanks
