Thanks to the help of these forum, i was able to connect my BeoLab 3 via Powerlink with my MX4200 and can listen musik, if i connect a player via the front Cam In with the MX4200 and choose CAMERA at my remote controll.
But I dont ike the cables in the front, is there no way to use the right Scart In to feed my MX4200 with music ? The left scart in is already used for my set top box.
