I purchased "Independence Day" on DVD which said at the back of the box that it has a DTS sountrack. However, when I played the disk at home, there was no such DTS option, just the Dolby Digital 5.1. It's onw of those shops where the DVD boxes on the shelves are empty, and the disks get put in the box when you take it to the counter. Did the shop-assisant put the wrong disks in the box (old release DVD with no DTS), or was it a misprint on the box and the disk isn't supposed to have a DTS option? If it's the case of the shop assistant putting the wrong disks in the box, how does he identify which is the correct disk to give me? I'm guessing he got the old-released disks mixed up with newly released. Thanks.
