iTunes 10 Video Size Grayed Out

[Plutonius]

Any idea why the video size menu (under the view menu) is grayed out ?

It doesn't seem to do anything if you've set your videos to play in the iTunes main window. Switch it to play in a separate window if you really want to see what's in that grayed out menu. (Preferences > Playback > Play Movies and TV Shows > in a separate window). And then, of course, start playing a video.
