Hi there...I think that in Spain they are selling the German version. My reciver detect Master audio in German. In english and the rest it is on regular DTS with 6 chanels. From the back side of the box you would think that are all master audio which is not true.
Unless anyone actually has a 6.1 setup at home (And I really would bet the house on this that you haven't) its a complete waste of time releasing these films in 6.1! 6.1 is the Jar Jar of sound formats!
