Here's the setting.

I'm watching Sky+ on my BV8, I mute the picture and turn on my BS4 to listen to a CD. I then turn my BS4 off and want to control SKY+ again, however when I press the DTV button on the Beo4 it switches my SKY+ box off.

Is there any way I can stop it doing this without putting my hand around the top of the Beo4????
