the Beo5 IR Command: "Sound" changes Speakers Mode. The IR Command to change languages on TV with Beo5 is "Turn".
That's very curious !!!
I think all it's due you have a BV7 and I have an Avant, because in my case Beo5 works exactly as my Beo4:
Beo5 "Sound" command change languages in tv dual channels, and "Speaker" the speaker mode...
In my beo5 the "Turn" command doesn't exist !
Anyway, the only important thing is that now everything works for you Quim...
Regards.
