I need to know a bit more...
Is there a ML link between the Ouverture and the Beocenter 6. Which on is the audiomaster?
Which mac are you using? In which room is the mac and Beoport installed?
Your B8 is not connected with ML, is it because the TV does not have a ML module, or is it just you haven't connected it?
You'll find on this page how to contact me and send me your answer.
