well you maybe noticed some inner circle.. but thats not the part that do it
on original disc the part i mean looks allmost!!! the same
only when you watch good an change your position of holding the disc you can see there are different circles on the disc..
but it should be dumb if sony did make the bluray protection so easy to hack to
so i don't think it wil be broken so easy. but maybe help in some cases..
best regards,
