My buddy was over last night and we were playing on LIVE against some friends. First time we were both playing on LIVE via split-screen. Only one voice communicator would work though (mine).
We were signed in under my gamerag, JediJurist, and my friend's player name was "1 JediJurist" (and it had a tiny image next to the name that looked like a person's shoulders and head).
We tried to figure out a way for him to sign in under his gamertag simultaneously with mine, but it wouldn't seem to work. (We were playing on an original Xbox).
Any way to get both communicators working?
