Yes, this is possible in the OPPO 203. Assuming that you're doing Zoom Method CIH, set the aspect ratio setting for "21:9 Cropped" in the player's menus. Immediately, this will pillarbox a 16:9 input signal into the center of the 2.35:1 portion of the frame. Then hit the Zoom button on the remote to get to the "21:9" setting, which will fill the width of the screen while blanking off the top and bottom.Also, when watching variable aspect movies such as MI: Fallout, are you able to use the player to mask the top and bottom of the image and keep it in 2.35 aspect? Thanks for any info you guys have.
