Wanted to post an image, but new users are not allowed. The pic is a screen cap of an mkv file that is running in ZOOM player, it shows two frames stacked vertically. The file will do the double frame in all players, I tried it with VLC player also. Has anyone seen a video file play with two frames stacked vertically like this before? Is there a way to get it to play normally on one screen? Changing aspect ratio does not work. I have a slow computer would like to avoid recoding the movie again.
