Possible solutions could include checking the video player's subtitle settings, ensuring the correct subtitle file is used, converting the subtitle format if necessary, using different codecs or players, and adjusting system regional settings for proper script rendering.
Wait, but how does the SXS in the video files affect subtitles? Maybe the subtitle is embedded in a specific way that some players don't support. Or the subtitle file is stored alongside the video but the player isn't linking them correctly. Also, Hindi uses a Devanagari script, so font issues could be a problem if the system doesn't have the appropriate fonts installed.
Time-stamping issues: The subtitle files might have incorrect time codes or be misaligned. Using an editor to adjust the timing could help. Tools like Subtitle Edit or Aegisub can be used for this.
I should structure the essay with an introduction explaining the problem, followed by step-by-step solutions. Each solution as a section with explanations. Maybe start with software solutions (players, settings), then move to system settings, and perhaps include some tools that can help. Also, mention checking file compatibility and codecs.
Another point: sometimes the subtitle file might be in the wrong encoding (like UTF-8 vs. ISO-8859-1), and if the player is reading it incorrectly, Hindi characters might not display. So opening the SRT file in a text editor and saving it with the correct encoding might resolve the issue.
