This is wonderful. I was tinkering with it, and I discovered that this works only with the "main" display, not with the "cinema" display or anything, so I, for instance, have to do something like this (while PAL is selected in the settings):
"echo ntsc > /sys/devices/platform/omapdss/display1/timings & echo 59,30 > /sys/devices/platform/omapdss/overlay2/position & echo 640,500 > /sys/devices/platform/omapdss/overlay2/output_size"
While the film is running (like in Kmplayer and SiB or Mplayer) to make the screen resize.
I was also trying to work on how to crop and resize at the same time, but no luck till now.

I would love to see anything like that (Vert and Horz resize + crop) in any future improvements of this widget.

BTW, I like this as an widget... Its far more accessible this way, for everyday use...
