I have burnt Killzone, online it works(I have yet to try it online as I havent got past my pin, so my sony login won't work until I get it. It gets past the DNAS test anyways) But it took a few attempts to boot, the third it was fast but then it slowed down on the loading screen with the bar. Then it speeded up at the menu. In game I cd not use te x button to climb etc and when I paused the game it froze. I tried it again and got the same effects. When I was burning it I was on MSN, the internet & watching Red vs Blue. Would them things running interfere with decrypter in anyway.
