Brilliant idea just occurred!Build a lag switch. When he gets annoying, flip it and he will be disconnected. Solves your problems.
My problem is that I want to hear the sound from the computer and not hearing the sound from the xbox.
When it lags out, it usually goes back to the title screen or the lobby which usually have softer music playing if any at all.
But he will rage and talk to his handicap over the phone
Punch him in the face
Your Brother: I want to play Xbox 360 60% percent of the day!You: How about 60% of my foot in your ass?
I see. Maybe you could convince him to buy some headphones that he could plug into the TV?
just buy him the headphones so he can shut up
alright, fixes that problem I guess
Or convince your parents to buy him the headphones or something.
