Aspect Ratio 1.85 and 2.35
 

maybee you should insert some aspect ratio's like 37:20 (1:85) and 47:20 (2.35) under Shift +4 and Shift + 5, because a lot of movies i watch are in that aspect ratio.
Also i wanna say that if i custum pan scan in full screen mode, and go to window mode, and then i go to fullscreen again, it doesn't remember my custum pan scan...

You can cycle the aspect ratios under 'A'.

For 1.85 movies, use 16x9. It's the same ratio.
For 2.35 movies, I use my custom aspect ratio : 20x9. It works great, and it also stretches the movie to a bit larger size without ruining the picture.

I've posted a reply to the same problem in another thread.
