Plex does two things I like – one, it nicely saves “where you are” in a particular program across all platforms using Plex, and two, it will play subtitles.

I have tried VLC as a client/program but it’s not nearly as elegant as Plex. Chris, what program are you using for the file remux? I’m not familiar with tx3g – is this embedded subtitles or are you downloading the subtitles via AS as a separate file? I might try this especially with 1080p files. – 480i) seem to work fine on the Fire TV 4K stick.

So I use that for Plex streaming of the AS files. The Tivo box, for some reason, handles the MP4 AS files reasonably well. When I play 1080p MP4 AS files, it will play fine for maybe 15 minutes or so, then it will start with the buffering/stuttering issues. In most cases, M2TS 4K files will play OK also although I have had occasional issues. When I use the Fire TV 4K stick, M2TS 1080p files (direct rip from BR) play just fine. I either use a Fire TV 4K stick or Tivo Mini box as the platform for the Plex player.
