Pretty reasonable question. Let me see if I can clear it up some...

Quote:

If I buy a DVD-A or SACD where does the sound for the rear channels go? Do I have an option to route them to surround / rear surround (speaking 7.1 setup)?


If you are using the 6-channel analog input (which with DVD-Audio and SACD is what you want to do, so you get full benefit from those formats), then the surround back channels (speakers "6" and/or "7" in a 6.1 or 7.1 setup) will not get any signal at all -- both formats are limited to 5.1 (mains, center, surrounds, sub).

The only info I found in the manual was a reference to not even use the analog inputs, but instead use optical in to let the 950 decode the signal.


What you found is referring to the way the 950 handles either digital inputs or analog stereo inputs (such as the signal from your VCR or CD player) in regards to surround modes. The 6-channel input the DVD-Audio or SACD player will be using is not processed by the 950.
