It is typical to have all 2ch Dolby Digital signals 'spread around' by ProLogicII processing. As far as I can tell, there is no simple way of doing this _automatically_ with the 950.
From what I can tell, you can setup the 950 to either (1) force to a specific input protocol (PCM,Dolby-AC3,DTS) or (2) let is automatically sniff the bitstream and figure out which one.
Of course, I expect like nearly everyone else, I have to set the digital input to 'auto' since the material I send from my DVD player varies from PCM to DD to DTS.
The problem of course is that DD 2ch material cannot be 'upgraded' to 5ch surround material. I have to walk over and manually change the setting. Is there any way to do this automatically, any sort of software upgrade?
I strongly recommend reading here to understand better the very common problem I am facing, and a competitive solution I am hoping you can clone (the Anthem is rather expensive!)
