Query: Great movie; don't waste your money on the Blu-Ray

"The King's Speech" is a great movie, but the Blu-Ray disc is unplayable on many popular BD brand players, such as Samsung (my experience) and LG (read the other reviews). Apparently the copy protection on the disc is so strong it fools the players into thinking they don't have enough memory to play it. My experience was that the player took nearly ten minutes to grind haltingly through the first ninety seconds of the movie. To add insult to injury, a group of inane movie previews you are basically forced to watch before getting to the main menu play fine. The DVD is nearly as good quality and plays fine in any DVD or BD player. Don't waste the extra money on the unplayable Blu-Ray disc!
