AVI short for Audio Video Interleave is a common video format that you see a lot when downloading videos, movies, tv shows, cartoons, anime or other types of videos.

SRT short for SubRip text is perhaps the most common subtitle format used with AVI movies and videos.

So when you added your SRT subs to your AVI file, the subtitles don't show up while playing an AVI movie or video on your device.

The solution is to merge (combine) the AVI file with the SRT subtitle file to one file.

With the free and small program AVIAddXSubs, it only takes about one till two minutes.
