i keep having problems with playback of bluray. some movies i just cannot get to play with out any hang ups. for instance i watched captain America with out any problems then after that i watched horrible bosses and the powerdvd completely froze about 1 hour into the movie. i had to ctr alt del out of it. when this happened i noticed the hdd activity light was solid, not flashing it was just solid. i had this happen with a few other movies in the past like the lincoln lawyer would hang in multiple places.
