Query: Great movie, HORRIBLE BLU-RAY DISC

Be very careful when you buy this blu-ray, will not work in some Sony 3D blu-ray players, and some Samsung. There are some work-arounds online, but they don't always work and who wants to do that everytime. It's too bad Fox really dropped the ball on this blu-ray, it is a great movie.
