I'm terribly sorry if this request is already posted, but the thread was sooo long...

I would very much appreciate a "zoom" feature. It enables you to crop the movie so that it will fit the entire screen on your device. No math or magic, you get a nice preview that shows you how the movie will look on your device (in my case a PSP).

Typically, it will chop off the left/right edges of a 2.35:1 move so that it will display full screen on say a 16:9 display. This is quite handy on i.e. a PSP, where screen size is limited. Subtitles should be rendered after the cropping, so that it works well with both wide and tall (4:3) material.
