Hello!

I have e Bv7 mk3 and two bl4's as surroundspeakers. When I watch a 2.0 source the rear speakers are off (red light). If I then switch to a 5.1 tv-program or dvd the rear speakers automatically go green and start to work. All is fine so far.

But if I the go back to a 2.0 tv-source, the rear speakers are still on. And if I check soundsource in the menu i says speaker 5. My defaults are speaker 3 for video and speaker 2 for audio. In this case I have to switch the tv off to stop the rear speakers from giving sound.

Does anyone know why this happen?

The same thing happens to me.  I've been told it's normal

... or press "LIST" on your Beo 4 till "SPEAKER" is displayed and then press "2" or "3"

I have a Beo5, how do I do this? And is this really to consider "normal"?

Yes.

Everything is depending on the programming/config of your Beo 5 ...

Selecting a video source like "TV" you should find it under "Scene" 
(maybe also on a secondary page of "Scene")

Find "Speaker..." select it and then press "Mode 2" or "Mode 3"
