I just installed a F90BT and for the life of me, I cannot get the subtitles off when playing a DVD. I have gone into the FUNC and DVD Setup to verify the Subtitle Assist is off. Am I missing somethig?

when watching the movie, bring up the play/pause screen by tapping the screen. Then tap the arrow that faces to the right 3 times, you'll see it on one of the menu options.
