Well im running a high end setup too and on auto the display for ANH reads DD whereas the other 2 display DD EX. I must admit i am a big fan of DTS and dont get me wrong i love the tweaked DVD i just yearn for great movies to be presented in DTS eg SW, The Matrix.
Gladiator was a great visual transfer and had both DD and DTS so why couldnt GL do it with OT.
BTW what is your definition of high end setup????
