You need to use the "open BDMV folder" function in the open panel, and you need to choose the upper folder which contains the bdmv folder (with VLC 2.1.3).
yes, i agree with you, VLC 2.0 or later version supports the Blu-ray playback. However, for legal reasons, AACS and BD+ DRM libraries and keys still are not shipped. That means only Blu-ray disc with AACS libraries exposed are supported.
BTW, if you have problem, cannot play blu-ray with VLC, the follow guide may be helpful for you:
You'll need two files: keys database and AACS dynamic library.
Keys database
UPDATED 21-02-2016! get the file:
http://vlc-bluray.whoknowsmy.name/files/KEYDB.cfg
Windows: put it in C:\ProgramData\aacs\
Mac OS X: put it in ~/Library/Preferences/aacs/ (create it if it does not exist)
Linux: put it in ~/.config/aacs/
AACS dynamic library
UPDATED 22-02-2016! get that file:
http://vlc-bluray.whoknowsmy.name/files ... aacs.dylib
VLC 32 bit on Windows: put that file in your VLC directory
VLC 64 bit on Windows: put that file in your VLC directory
Mac OS X: put that file in ~/lib directory (create it, if it does not exist)
In this way, the blu-ray may playable on vlc. If mac users still have issues, please turn to
