Playing a BDMV/Blu-ray/AVCHD source was built so players use the entire directory tree which is why opening the main folder or `index.bdmv` is the proper method, while `.m2ts` files in `STREAM/` provide raw video for quick viewing, with the largest usually containing the main content; if playback is incomplete, the `.mpls` playlist in `PLAYLIST/` must guide the sequence, and complete failure commonly occurs when the structure is missing STREAM/PLAYLIST/CLIPINF or when the player can’t fully support Blu-ray, so keeping the directory intact and using a capable player is the practical fix.
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 a folder-based structure rather than a single MP4 because they were built as disc-style playback systems, with transport streams (`.m2ts`) optimized for continuous reading and error tolerance, separate playlist/index files to assemble segments into full titles, and navigation logic for menus and interactive features, creating a small "playback database" that a player interprets—whereas MP4 is meant to be one self-contained file for simple distribution and playback.
Opening the BDMV folder in a player allows accurate assembly of the movie because the player loads navigation files like `index.bdmv`, reads playlist instructions from `PLAYLIST/*.

A `.bdmv` file isn’t the video itself because it serves as a Blu-ray/AVCHD control file—an instruction guide that tells the player what content exists, how playback should begin, and how to navigate; the real audio/video lives in `.m2ts` files under `BDMV/STREAM/`, with playlists (`.mpls`) and clip info (`.clpi`) defining order, timing, and sync, so you can’t open a `.bdmv` expecting a movie since it mainly points to the streams rather than containing them.
You usually can’t open a `.bdmv` and "see the video" because it’s a navigation/control file, not a media container, with the real footage living in `.m2ts` files under `BDMV/STREAM/`; playlists in `BDMV/PLAYLIST/` and clip info in `BDMV/CLIPINF/` define how segments join and how seeking works, so a lone `.bdmv` has nothing to decode, meaning you must open the full BDMV folder or the actual `.m2ts` streams to view the video.
