Sometimes when you try to download a movie or some specific video using Elmedia Player you can find out that it is divided into several parts of unplayable format. Such issue usually occurs if the video is provided by a website in segments but not in a single stream.
In fact such videos can be downloaded by Elmedia Player, but unfortunately after downloading all segments will not be combined into a single movie. These segments are also cannot be played due to their format. However you may try to rename downloaded files to .flv and open in Elmedia Player.
