A very odd problem. Beosystem 3 connected to a BC 2 and Beosound 9000 in main room, with a Beolink Active and Bablab 4000's in link room. System has been working fine up until a few weeks ago. Now what happens is as follows. All video prompts work with the Beosystem 3 including DTV with a Samsung TV. No response from the Beo4 when Aux (apple Airport Express), or CD is pressed. I cannot even turn the BS9000 off with the Beo4. I need to use the local button. When I press the disc button on the side of the BS9000 the disc will play but not in the main room but the link room! The aux will not operate at all. It used to play music from my Mac iTunes. I have tried all the logical steps but cannot isolate the problem. I might add that nothing has changed with the setup lately except having the BS9000 receive a new laser. Any insight would be appreciated as I have run out of inspiration. paddy2042
