This is a known issue with the disc that has popped up only recently. But it is an disc authoring issue that FOX has taken responsibility and even set up a disc replacement program for:
From the Digital Bits (back in 2011):
"Finally this morning, those of you who are fans of Fox's Sunshine on Blu-ray - and have Sony players (or the PS3) recently firmware upgraded to be Blu-ray 3D compatible - will no doubt be aware that there's been some problems playing the Sunshine disc since the upgrade. The resolution to the problem apparently requires that Fox reauthor the disc to be compatible... and thanks to the lobbying effort of a group of fans of the film on Facebook, the studio has now done so. To arrange a replacement copy, call 1-888-223-4369. They'll need your name, mailing address, and the make/model of your Blu-ray player. Replacement discs should be mailed out in 1 to 2 weeks.
