Halo 3 on xbox live fucking up

[Solve et Coagula]

When I enter the first lobby(where you select what kinda of match etc) then hit Start it will take me to the next lobby where it searches for players. Finds all the players etc, shows me the map/game type then about 5-10 seconds after that it boots me back to the first lobby. I know its not my Xbox live, since it works with other games. Could it be my Halo 3 disc? It has some slight scratches but nothing major.

Halp Im bored and wanna play halo

[DrSupey]

your disk is scratched

try using sandpaper to get rid of the scratches (circular motions around the entire circumference of the disc only)
