I can play any other game except for COD MW2 and Black Ops Online.

When it tries to find a game it just sits at the "searching for matches" screen and keeps climbing up the >ping list, to no avail.
I have Port Forwarding all set, I even bought the software from portforwarding.com because I thought I must be doing something wrong.
I have a DMZ set for the PS3.
I have tried both Wireless and Wired

Where do I go from here?
