+If you have found that your device has limited handling of video aspect ratio, then you can tell Mezzmo to auto correct the aspect ratio for all videos that you stream to this device.  This means you do not have to manually pre-transcode your files to fix aspect ratio issues as per Step 2.  Mezzmo will set the aspect ratio to SAR 1:1 square pixels which should be displayed correctly by all devices.
