I recently went to my local Sam's club and picked up "The Abyss" special edition THX wide screen for $13.99. On the back it states English 5.1 Dolby surround and English Dolby surround. I pop the disk in pick special edition and the audio setting and no 5.1 option only pro-logic. I flip back to the menu and picked the theatrical edition and audio option and again no 5.1 only pro-logic. I have check other web sites (Amazon, DVDempire etc ...) to verify and they all say 5.1 Dolby and pro-logic. Did I pick up a bad disk or am I going crazy? Thanks in advance for any info.
