SilverWook,
Yeah, it was released Theatrically with 5.1 Dolby Digital.
The DTS mix is authentic according to IMDB which says that it was released in Dolby Digital , DTS & SDDS.
The link I Posted was just the 2.0 Pro logic mix that was on the DVD(Converted from AC3 to Flac) Most Older Fox DVD's came with 2.0 Pro logic tracks.
Let me know what you think about my FLAC rips!
