I figured I would ask all of you guys... I recently got surround sound and have been very satisfied with it. I have upgraded my Saving Private Ryan and Jaws to DTS versions. My question is: Are Jurassic Park and the Lost World worth upgrading to DTS versions? Is there really an audible difference between the DD and DTS versions? Note to respondants: Please do not bring this to a "which is better? DD or DTS" thread. I would like an honest answer. If there isn't much difference, that's fine. If there's a big difference, please let me know.
