Playing a BDMV/Blu-ray/AVCHD source expects all supporting folders to be present meaning the best method is opening the parent folder or `index.bdmv` so the player can follow the disc’s layout; `.m2ts` files in `STREAM/` give you the footage directly, and sorting by size helps find the main video, but fragmented playback usually signals that a `.mpls` playlist must be used; failure to play often stems from missing directories, renamed files, or a player lacking Blu-ray support, making it important to keep the structure intact and try a compatible player.
Inside a typical BDMV folder you’re viewing a system where several folders cooperate, where `STREAM/` carries the `.m2ts` video/audio streams (the largest usually being the main program), `PLAYLIST/` holds `.mpls` instructions telling the player which segments to combine, `CLIPINF/` contains `.clpi` data that improves indexing and A/V sync, and navigation files like `index.bdmv`/`MovieObject.bdmv` define startup behavior and available titles, while optional folders such as `AUXDATA/`, `META/`, `BACKUP/`, and `JAR/` help with metadata, backups, or BD-J menus, producing a complete package for Blu-ray playback.
Blu-ray and AVCHD use directory layouts instead of a lone MP4 because they were engineered for disc playback: `.m2ts` streams support continuous reading and robustness, playlists join split segments, clip/index files provide accurate seeking, and navigation logic enables menus and branching, forming a multi-file system that players interpret, unlike MP4’s single-file approach aimed at convenience.
Opening the BDMV folder in a player lets the program read the complete navigation system since it scans `index.bdmv`, loads playlists from `PLAYLIST/*.mpls`, and uses `CLIPINF/*.clpi` to map out which `.m2ts` files form the main feature, giving you clean chaptering, proper audio/subtitle handling, and seamless transitions—unlike opening a single `.m2ts`, which might show only one segment; selecting the folder with `BDMV` via Open Folder/Open Disc lets the player build the full title for playback.
A `.bdmv` file acts as navigation logic rather than storing video and audio, describing what titles exist and how the player should start or move between them, while the genuine media is in `.m2ts` files inside `BDMV/STREAM/` and supported by `.mpls` playlists and `.

You can’t usually preview video from a `.bdmv` because it’s part of the disc’s control system, not a container with audio/video, whereas `.m2ts` files in `BDMV/STREAM/` carry the real footage and `.mpls` playlists plus `.clpi` timing info assemble it into the proper title; a lone `.bdmv` has no media content, so opening the full BDMV folder or the `.m2ts` streams is the reliable solution.
