I am unable to select music of my choice or change to nettradio using Beo4 in link room. In order to activate speakers I need to choose Data in Beo4 and then select the songs from left/right or updown arrows. I am unable to select a perticular CD from Beomedia1 or change to nettradio in link rooms. I have connected the BeoMedia1 to TV and to Beo wireless1
