I don't think so. That should be real only for videos at 320, 512, 640, 800 and 1024 pixels width. To match the exact size of the screen. And what about 1920x1088 resolution ?
Or 352x288 ?
In that drop down box you can see all those resolutions that are normal for a 4:3 display (this is called aspect ratio). Few files have such a resolution and such an AR.
Maybe this is for slower computers where any lowering in resolution can improve playback rate. Don't know for good. Maybe someone will explain us exactly.
