Problems

The game will sometimes freeze for a few secounds but i can still hear everything or it will kind of stutter and get me killed. Im also having problems with loading in custom games (few maps) at the start of every round where like the last problem i can still hear everything but im still on a loading screen longer than others once again getting me killed. I know its not my connection which makes me wonder if my xbox is getting slow or is it the game. Anyone else with this problem.
