Playback issue on Android TV app

If it is MP4 we can try anyway.  You copy and paste the code block into a Linux terminal or Windows command prompt.  You'd have to adjust the file paths to match your operating system and the actual path for your video file.

Like this? I'm on Windows.

/usr/lib/jellyfin-ffmpeg/ffmpeg -fflags +genpts+igndts -i "F:\Movies\Live-Action\Underworld Collection\[#01] - Underworld (2003)" -avoid_negative_ts make_zero -max_muxing_queue_size 2048  -map_chapters 0 -c:v copy -c:a copy -c:s copy -c:t? copy newFile.mkv

And than press Enter?
