This Blu-ray Disc needs a library for AACS decoding, and your system does not have it.
Your input can't be opened:
VLC is unable to open the MRL 'bluray:///F:/'. Check the log for details.
To resolve head to vlc-bluray.whoknowsmy.name and download two files: KEYDB.cfg and libaacs.dll.
Place KEYDB.cfg in %APPDATA%\aacs folder. Normally:
