The movie was mixed for EX, but the DVD is not properly flagged. You
have to manually engage EX decoding on your receiver.

I find that it's usually best to just leave EX on all the time. Even
movies not specifically mixed for it will often matrix well into the
center back speaker.

I leave mine on to, but it is kind of odd that the THX trailer has a flag
that my receiver recognizes and the movie does not.

along the same lines, I've noticed something else I've wondered about. Aside
from the star wars disks, I have a good many disk that are EX encoded. When
I play these the little graphic that most receivers have that displays the
speakers engaged does not show the center back speakers engaged, but the
receiver has recognized the flag and the decoder is on and working. The only
disk I have that show all speakers (in the graphic) are the DTS 6.1 discrete
ones. I just got Charlie and the Chocolate Factory which is EX and it lights
up all the speakers in the graphic like the 6.1 discrete ones and does
engage the decoder. No big deal - just something I've wondered about. My
system is a 7.1 one by the way if that matters.
