Hi have same probs with game play on blackops seems to be problem with blackops its self. What I used to be able to do was put the mw2 disk in the play station.play one game and then go on blackops, and that would sort out the strict Nat prob. As for lag issues try changing search option in blackops to local. everyone on ps3 has issues with this game.
