It seems like you might run into issues if I'm understanding your setup correctly.

Movies:
  A:
    A movie starting with A.mp4
  B:
    The Blues Brothers (1980).mp4
    Blues Brothers 2000 (1999).mp4


Jellyfin works most effectively with a flat structure, where each movie has its own folder. Please refer to the guide for more details.

Example of using the tmdbid:
Blues Brothers 2000 (1999) [tmdbid-11568].mp4
