At this time, there are no discrete codes for individual surround modes - all we have are the three mode buttons (Dolby, DTS, and stereo). There have been several requests for a remote command that would scroll the current mode information across the front panel display without changing modes, but we'll have to wait for the firmware update that is in development to find out if that can be added. Since the remote layout is fixed, it would have to use an existing command (such as the navigation "up" button, which does not do anything unless the 990's menu is active).
