I recently purchased black hawk down for DVD and the sound is lacking things that i heard in the theater. I watched it in a THX teater in NYC. For example the copper noises are almost gone in the scene where they are flying by the beach toward the moge. My theater isn't exactly thx stuff but the dvd seem to be lacking deep bass. It just does not sound as full. has anyone else notice that or is it just that my subwoofer sucks.
