Unfortunately, I have problems with fluidity on watching movies (from normal SD 480p to HD). The problem I think is due to FPS because many are at 23.976 while the format in Italy should be 25. Practically every now and then you see a shot in the frame of the film in view, especially if during viewing I display the info or send the movie back or forward. What settings could I try to setting? If the display refresh rate (always) is enabled in the display setting, the screen will turn black. I ask for help!
