To my regret I have discovered that these Blu rays are Area 2 and unplayable in the U.S. Nowhere on the set does it say anything about area; it merely lists the format as "BD50x3 & BD25x1." However the BBC's website lists the set as area 2 -not the U.S. It is conceivable that some U.S. players will play these discs, although my Denon DBP-2010ci will not. Of course, Amazon is good about returns, but they should investigate and change their statement that the discs are playable in all areas. Very disappointing because it was a wonderful program.
