Query: Great movie but the DVD is bad on a PC

Seen this show twice at the movies and bought the DVD today, picture is awesome but the sound sucks! The special effects are loud and clear but the dialog is so low I can hardly hear what they are saying over the special effect sounds. Tried it on my desktop (which has never had any problems playing dvd's) and my laptop, both have the same problems.. Not sure if I just got a bad DVD or not, going back to the store to exchange it for another.
