Exact same thing is happening to me, right when the match says Launching... it freezes. I asked last night, nobody answered. I have no idea what is causing it.
Did you have to download an new update before you played it? I did, but it was also teh first time I have played MW2 on my new PS3. Not sure if that has anything to do with it or not.
Mine freezes just as it finds a full party prior
to the countdown. When I try to Quit the game,
My PS3 reboots itself.
This seems to have been happening since the
last System Update ( 4.25 )
Anyone get it to work yet?
