How to view the downloaded film with subtitles:
Note that the subtitles are not embedded in the downloaded video file, you will need to download the subtitles.
If using VLC Media Player, after opening the film, you can right-click the player window and select Subtitle > Add Subtitle File, then browse for and select the subtitle file you've downloaded.
If not using VLC, ensure the film and subtitle are in the same folder, and that they share the same filename, e.g. Dominion.mp4 and Dominion.srt. The subtitles should then automatically be included when playing the film in any other video player software.
