Whenever I play DTS-ES, the display panel always says "DTS ES." But whenever I play a movie with DD-EX, the display is still "Dolby D." How do I know that it's picking up on the EX and not just giving me the normal 5.1? Do I need to switch it over so that the display says "6.1" or is that just for when you want to receiver to do the fake matrix? I guess the Auto Flag detection still confuses me. I've been wondering this for a while but just recently became a forum member.
