Less wear and tear on the JVC motor as well for zoomers.Think you misunderstood. You are still zooming out with the JVC. You're just telling the Oppo that you are zoomed so it makes the menus fit the 21:9 aspect you now have and it crops the image so no overshoot (just black). And because it knows your aspect now, it allows you to have instant 16x9 image without having to zoom back so you can see menus or even watch content that way if you want. So still zoomed out, player just making it easier to use this method without an outboard video processor.
