Thanks for the reply Gonk, I will do a proper test tonight to see exactly what it is doing with certian settings; once I noticed that it was acting odd and not letting me keep a setting I was trying all different kinds of combinations including sub settings. What I found most odd was that it would toggle the settings on its own; for instance in the Speaker Size Menu I would arrow over and set the surrounds to large and and then it would "pop" back to small on its own. I had a very hard time setting the center channel to "None" and had to go in and out of the Menu a few times to get it to take. This has nothing to do with bass mgmt or sub setup since its just a configuration parameter so why would I have problems setting it to none? You should be able to "disable" a channel by setting it to none, even if speakers are connected correct?
