i have noticed a lot of blu-ray movies (especially lions gate releases) show dolby digital ex and dts es or hd tracks on them. do these movies not have regular dd 5.1 and dts tracks on them? i ask because my receiver only has decoders for dd5.1 and dts (regular). i know, i know, it is old. does this mean i am screwed if i want to watch these movies? or is there some way that the ps3 can send the sound to my receiver and i can still get true discrete surround sound with my pitiful old receiver?
