Our son likes toy story 3, which we own in the blu-ray combo pack with blu ray, DVD, and that other digital copy whatever disk. We brought our MacBook on a plane trip along with the DVD. Not the blu-ray. Well, it plays the previews, runs the main menu, but when the movie itself starts, it's beachball of death land and force-quit is required to kill DVD player app. Same DVD plays fine in a home theater. Any ideas? Is this disc "forbidden" in computers? Is it designed maliciously by disney to crash computers?
