Ensure the subtitle file has the exact same name as your video file (e.g., K-9.1989.720p.BluRay.x264.[YTS.AG].srt ). Placement: Keep both files in the same folder.
If they don't appear, simply drag and drop the .srt file onto the video player window while the movie is running.
Open the video in VLC Media Player or MPC-HC . The subtitles should load automatically.
