I think it only looks like it moves it correctly.  The only reason it does
that is that it scales the video down vertically which moves the OSD down/up
on the screen.  When you scale up vertically, the OSD would move off the
top/bottom of the screen as it does in the zoom modes.  That's because the
OSD is drawn on the video and then the video is scaled in hardware.  In
order to keep the OSD in the proper position and size on the screen,
the OSD will have to be drawn at a different size and location on the video
to account for the video being scaled later on to something other than the
4:3 the OSD assumes it will be scaled to.
