I’ve made a test of all four options and I’am afraid it does’nt work. I don’t hear any difference enabling any of them. Watching movies at night I still can’t hear dialogues well. Is there any chance to fix this problem? It is really annoying. I don’t want to sell my media player because I think it’s the best media player in the market but I want to delight in watching movies as I did it using my old media player Xtreamer Sidewinder. I hope you will fix it. I’m waiting for any answer.
