Thank you Andrew.
Does that mean, that I need a second MD in Room #2, if I want to control the Squeezebox Receiver?
For Room #2, I currently have the Squeezebox controlled by the SlimServer and the Receiver controlled by the MD in Room #1. Shouldn't this work. For me it looks looks like a similar problem described in the wiki (http://wiki.linuxmce.org/index.php/Rooms
), where two EAs exists and they share a DVD. But regardless, what I setup, either I do not get the Audio scenarios for Room #2 or the system is controlling the stuff from Room #1, if I choose Room #2.
Hmm, I've to dig deeper into that problem, hope that I can get it to work.
