Now everything work fine. I can control via Beo4/5 my iTunes 7.7 with BM-Link 1.5.2. But the next challenge is just around the corner. I have a BC2 (just for Radio) in the main Room and in the other Room a Beo PCPort with BM-Link (Firmware 1.3), IR and BeoLab3 (connect to my iMac). But I could no control the Radio from the BC2. The other way work perfect (access to my iTunes in the main Room over N.Music).
I try some Link Option (6), but no success.
Any Ideas ....
thx Thomas
