Most video player plugins need about 20 pixels of vertical space for a control bar (stop/start, slider, volume). The ogg handler is setting the height to the exact size of the file, which can lead to some visual unpleasantness with cropped or stretched video -- even a cropped control bar with the QuickTime player. :)
I'm not sure if there's a really clean way to do this, but a reasonably safe bet may be to just add 20 pixels to the height.
