So I'm in the right zone. I then go tools/options/general/features and disable video support. This is then disabled in all zones. No matter which zone I re-enable it in it get enabled in all zones.
OK I think I have been misunderstood.I have the audio output sorted for different zones. What I wanted to do is not have the audio library visible in the video zone and not have the video visible in the audio zone. Cheers
