Plex Won't Recognize or Play AVI Files - Possible Reasons

Why your AVI files not showing in Plex library or Plex can't play them at all? It can be caused by various reasons. Maybe it's an issue of your file names, AVI video format compatibility, or the AVI file type etc. To be specific, there's a number of potential scenarios how Plex not working with AVI:

Reason 1: AVI is a container format, which can contain varied types of video codecs, subtitle tracks, audio tracks, etc. Though the most common used codecs like DivX, XviD are supported by Plex, some minor factors such as AVI bit rate, frame rate, resolution, audio codec also matter a lot when it comes to AVI playback on Plex.

Reason 2: Plex TV show naming will be ignored in movie libraries. That's to say, if you have some TV shows AVI files, they won't show in Plex library.

Reason 3: Poor named AVI movies might have been matched as a different movie. If random named AVI video not showing in Plex, you may find it in "rencently_added" column.

Reason 4: AVI files following the naming convention for multi-file movies end up as a single record in your library (e.g. Movie Name-part 1.ext and Movie Name-part 2.ext will result in an entry called Movie Name which will play both entries in sequence).

Reason 5: Depending on your library settings, movies might be automatically associated with a collection and only display inside that collection.
