So I received some more movies in the post today. I have a copy of Underworld Evolution (region B officially - but its actually region free) Anyway the movie will not launch in my 60GB USA PS3 ? It starts reading the disc and then a few seconds later boots back to ps3 XMB. The other movies I received all work perfectly and as normal, but this just wont do anything. I have yet to try the disc on my Euro PS3 as I'm not at my apartment today, but will try later when the mammoth storms outside die down and its safe to drive. Has anyone else experienced discs that just don't work on the ps3 ?
