When you play a DVD encoded in anamorphic or 16:9 aspect ratio you may need to adjust the following settings: If you play an Letterbox(LBX) format DVD title, change the format to Letterbox(LBX) in the projector OSD. If you play a 4:3 format DVD title, change the format to 4:3 in the projector OSD. If the image is still stretched, you will also need to adjust the aspect ratio.
