On my 950 I was able to set it to change formats depending on what source was playing. FM is in DPL-IIM. Cable is in DPL-IIC. When I select DVD and Play a CD, the source shows DVD PCM 44.1 and I have this set to stereo. When I put in a DVD it shows DVD only and I have that set to Dolby Digital. I do not have to change formats manually when switching from a DVD to a CD in my DVD player. You do this by playing a CD in the DVD player and going to the 950's "Input Menu" and selecting "stereo" for DVD PCM 44.1.
