Hey MCWHAMMER, I got your invite this morning.
I have pretty much been playing COD4 almost non stop on the hardest setting since I got it last week and I havnt seen any type of lagging, freeze ups or shut downs ((knocks on wood)). So what you are saying is that its a possibility that it is perhaps a bad batch of COD4 copies? It would be nice to know if it happens at a certain part of the game but none of the postings that I saw mentioned the spots that these things are happening in.
