Mismatch aspect ratio picture allignment

[Totanka]

If the screen's and the movie's aspect ratio doesn't match I would love to see an option to allign the movie to the top or bottom, while fullscreen. I have a 16:10 screen with a 1920x1200 resolution, and when I watch a 16:9 1920x1080 movie there is a 60 pixels blank area on the top and the bottom. One line of subtitle can perfectly fit into that 60 pixels (default settings), however if I could allign the movie to the top, than the bottom 120 pixels would be blank, and it would be just a perfect black background for two lines of subtitles.
