Gonk...
One monitor out is sent to a room with 7.1, with the audio signals routed to a Niles switching system. BTW, the 7.1 audio is actually split to THREE individual rooms (one is purely 7.1 audio). The other (third) video room has a projector, which has both s-video and componant video being sent to it. Thus the monitor out sv and componant 990 outputs are sent directly to this projector room; the composite output is sent to the other video room; and the 7.1 signals are sent to Niles A/V swithers to switch between each of the three rooms.

On installations we do, this is actually not that unusual a setup. Niles a/v switchers are extensively used for multiple 7.1 rooms. The hope was to use lcd monitors in future installs as well.

I suppose I could put ANOTHER niles a/v switcher between the "monitor" and the composite video in the other room, but wanted to avoid this if possible.

Hopefully this feature will be incorporated in a 990 firmware upgrade (if the latter would be theoretically possible...)
