they actually cant cut your service speeds because you are under a signed contract of that service. yes I know in fine print that they say speeds may vary but the FCC actually ruled in favor of the people saying filtering ISP service is not legal and unconstitutional. So this is obviuosly not the case here.
Especially since this is the only game for xbox that there is CO-OP Lag of this extremity. So therefore it has nothing to do with xbox live ports. If it was then there would be a lot more games having this issue.
