I have 2 DVD's that can only be heard in mono, not even stereo let alone 5.1 surround. They are Conan The Barbarian Collector's Edition and Jaws 2. My question: Why do they only have a mono audio track? I'm not certain, but I think the videotape versions of these same movies were at least available in stereo. I could be wrong! Conan is a good movie, one of Arnie's best in my opinion and it features a great score by Basil Poledouris. It definitely deserves the 5.1 treatment. Jaws 2, while not as good as the original, still has its moments.
