When the 950 acquires the signal, it tells you if you're getting Dolby 2.0, or Dolby 3/2.1. Then if you change the volume, it tells you on the OSD what processing it's using.

>The Bigger Issue:

I'm assuming you're using the same digital audio input for all of these channels:

I was just playing with my system.
HBO was in DD 3/2.1
IFC was in DD 2.0
MTV(hits) was in DD 2.0

Here's my thought:
There are 2 different kinds of Dolby Digital 2.0:
Dolby® Digital 2.0 Surround and Dolby® Digital 2.0 Stereo.

If I set the input to "stereo", I get 2 channel (L and R) playback from all 3 channels.

If set it to to "plain" dolby digital
HBO: "standard" 5.1 dolby digital
IFC: what you were describing, sound mostly from center speaker with some sound from L,R and surrounds)
MTV: stereo L and R (what you used to get)

Most of the channels with 2.0 gave me the same bad results as IFC. Could this be your problem? Maybe more channels are now sending 2.0 surround, versus 2.0 stereo?

My 950 remains in stereo if I switch it to stereo on any of the channels and then change channels. As for changing from Dolby PL to Dolby digital, I think that's driven by how you have set the Input Config in the 950's main menu. If I set mine to Dolby Digital, it does what you're saying. If I set it to PLII, and switch to a 5.1 channel, and go back to a 2.0 channel it returns to Dolby 2.0. But, if I set it to PLII-CR, I get DD+CR on the 5.1 channel, and PLII-CR on the 2.0 channel. I agree--a little odd.

And gonk,
"I have Dolby 2.0 default to Pro Logic II with CES on the DVD input and I have any stereo signal (Dolby 2.0, PCM, or analog) default to Pro Logic II with CES on the cable box input."

I was under the impression that you can only have one default processing mode for each input. How do you have a digial default for DVD and an analog default? (Unless you use a different input for each format, such as video1 and video2).
