Basically, it concerns films that are opened via the "Media Center", not films that are opened or played from the Home Theater - I think that works! Why do you always have to adjust the aspect ratios when changing films? Why can't the x20 Pro (FW 2.3.10) temporarily remember and save this for every film? For example, I switch from a 4: 3 film to a 16: 9 film and then have to change the aspect ratio from 4: 3 to 16: 9. If I then switch back to a 4: 3 film, I have to switch from 16: 9 to 4: 3 again, etc. If I do something wrong, is that a mistake ?! I would be very grateful for your help or tip because this is a very impractical thing!
