You'd have to put the BC1 and the Beolink active in Option 5, not 6.
The BC1 will react to Video command, the Beolink active to audio commands.
You can't really transfer the TV or DVD sound from the BC1 to the Beolink active.
However you could get the picture of the main room TV/DVD on the BC1 and the sound of the main room TV/DVD on the Beolink 1... that is if you have linked them using an RF cable as well.
