ok so im trying to watch my burned blurays that are in m2ts files, with ac3 audio, in my audio settings i have dolby digital 5.1 selected which my television and surround sound both support but when i try to play the movie i get no sound, when i take th dolby digital selection off of my audio settings it plays with sound and it says dolby digital 5.1 when i click for information, is it playing in dolby digital tho? i dont think so, it should be selected in audio settings for it to come thru in dolby digital, can someone help me here please?
