I'm pretty sure you just don't know how to use it. Don't hold me to this but I'm 99% sure you have to be the host of the game. Now on CoD5, This can be done by having the switch on while searcing for games, You will be host of game if your switch works. If it says waiting for 5 other players Then you are the host, Now you can turn your it off. Let the game start and use the switch however you please... In the lobby, if it ever says migrating host while your hosting flip it on, Then flip it off after it stops migrating. Start watching at like 2:20. Not my video.
