Usually overscan is associated with CRTs where the width and height of the picture is adjusted to be behind the bezel, but in the case of a fixed pixel panel like a plasma or LCD the scaling you describe would be done. Reason is since the broadcasters use the overscan areas for various other things they are not very picky about what may end up there and without overscan you could have video noise showing up on the screen. Many fixed rear projection sets will have "pixels behind the bezel" so to speak. And you are correct in the odd scaling.
