Before the update, I can play m4v file just fine on EVO. However, I tried to play the movies I played before, it won't work now. The files are m4v. I used handbrake to convert them from mkv. " The file type not found" would show up when I tried to play it. I am converting one movie to mp4 now, try to see if it's the file type that prevents me from playing it. Anybody got problem too?
