Query: Great movie,GREAT problems w/Blu-ray players

Problems with playback,I thought it was my player,it has the latest updates.I have many reviews,and many people are having the same issues,with various players.Too bad!It looks like they were in a hurry to release this.I own many titles,and this is the only one with issues.Most dreadful:the time-line keeps popping-up during the movie,and the further you go,the more frequent the pop-up.
