Hi gonk,

With the center enabled I can turn the surrounds off, but the subwoofer changes from "yes" to L/R+Sub. I'm not sure if the other sub choices are also available, I'll check tonight.

Yes, bullet number two sounds like it should do what I want, I haven't thouroughly investigated what happens with the sub when setting the surround mode to bypass because I was under the impression there was no additional processing in that mode. I'll check it out.

What do you find out of the ordinary relative to the way things changed when I enabled the center channel?
