When I click on a movie (using my desktop machine) It will open like it's going to start and nothing happens. I noticed if I open the film up in subler and change it to stereo it will play, but if it's 5.1 or 6 channel it just won't start. The weird thing is movies were working fine on 12.1 until yesterday with no perceived changes to my setup. Any help would be greatly appreciated as I have not been able to figure this one out.
