I was wondering if anyone out there knows how to control the TV volume when the TV is "snapped". My wife wanted to watch a movie tonight and I wanted to watch the game. So we were going to watch the movie and snap the game with it on mute. But I couldnt figure out how to control the volume on the TV (snapped) portion. So basically, both the movie and the tv were the same volume so you could hear both instead of one or the other. Any ideas?
