Before you can add any subtitle file to any tv series, you must make sure the exact SRT file for the particular tv series format is downloaded from the right source. Below are the steps to add to any tv series/movie player you are using to start.
While installing SRT of the tv series, download and copy to the downloaded file to the exact file location of the tv series on your mobile phone or personal computer or television.
After copying to the same file location, the tv series might play alongside the subtitles without any further settings or configuration.
If step two above didn’t solve the problem, then after opening your preferred tv series player and tv series is ready to be played. Select option or tools, then click on subtitles then add the just downloaded subtitles to the player from its location, and it should start displaying right away.
And better still, if you are viewing with VLC on your Pc, you can easily drag and drop the SRT file over the playing tv series, and it should work correctly.
