I also get a message that some files will not play with mass on, so I have it turned off. But, I still can't play anything at all no matter what I try. Can you help me?
I see the file, but can't play it. It is on the media card, but can only be viewed through "explore media card" and not "open media card." There is no option to "play" in explore and when I try to use "open," it reads "unable to display file." What am I doing wrong?
