Are the demo games like motostorm suppose to play in dolby digital? when entering the game it says dolby digital in the bottom right corner of the tv screen but when playing it , it says pro logic on my av receiver not digital.

Yea my Motorstorm demo doesn't play in DD but my GTHD does.

Switch your display setting when playing Motorstorm to 720p. I know strange, but true. Several members on here reported as I did that Motorstorm was originally in DD5.1, but then having played it later on it was 2ch. I did as they said and it worked. Give it a try.
