Didn't know about this. But when I played my new copy of Ironman BD 2 days ago, the PS3 hanged on boot-up - first time I've encountered this. I did a quick on-off via master switch in the back of the PS3 and thereafter the BD played flawlessly. I must say this is the best sounding BD I've heard so far (the cave firefight when one terrorist began firing a .50 cal machine gun had my subwoofer pounding deliciously).
