This kind of on-the-fly cropping can't really be called pan&scan as theres 
no panning involved; you just get what happens to be in the center :-) 

With a 2.35:1 aspect movie this would probably result in noses talking to 
each other alot. Not a good idea really, but whatever you want to torture 
yourself with is none of my business. Just imagine how much of the picture 
you'll lose this way if the movie was shot on Super-35 and you crop the 
widescreen version of it.
