Note that you can left click on the sample rate to make individual on-the-fly changes or right click on the sample rate to make global changes. For example, if you want everything resampled to 96,000 Hz, then right click on any sample rate and select 96,000 kHz.
Thanks mojave (and everyone else).
It turned out that I was not able to activate the MC output's drop-down menu, due to a Windows 7 mouse setting. Rather than having to click on a window, to activate/focus on a window, I am set-up to only have to hover over a window, to catch the window's focus (comes in handy, when you want to enter data into windows, without clicking them to the foreground -- just hover over a partially hidden window, and type into it, without your window arrangement changing).
This mouse setting was not getting along with this particular MediaCenter's drop down menu. The menu would appear for a split second, and close. So I undid my mouse setting, changed the MC output setting, and redid my mouse setting. I would not have known that the drop-down menu was there, if not for your attachment showing it.
Thanks again.
