Clean your disk then install it to your HDD.
If your disk still doesnt work buy a new one.
Halo 3 shouldn't be run from the HDD, so don't do this.
First check your maps in custom games, if some don't load past 20% then you need a new disc.
By looking at your recent games you've only "lagged out" of about 10% of games, around 30-40% you've obviously quit after going negative and knowing you're going to lose. The other 50% you've won and haven't "lagged out" shockingly.
