I was at a friend’s house checking out his DVD collection and pulled this title to have a look. I immediately noticed the DTS logo on the top left of the front cover, but no mention on the back. I popped it in the player to see if there was a DTS track available. But, nothing but DD5.1. Is this DVD available in the DTS format? If not, then why is the red DTS logo displayed prominently on the front? Thanks!
