Are you, too, annoyed by how difficult it is to just play DVD video files from your hard drive? Simplify your life by adding "Play DVD with VLC" to the right-click menu of every folder in one easy step! Press Windows Key + R to bring up the Run dialog and enter the following command:
REG ADD "HKCR\Folder\shell\Play DVD with VLC\command" /ve /d "\"%ProgramFiles%\VideoLAN\VLC\vlc.exe\" -f \"dvd://%1\""
That's it! The effects are instant; try right-clicking on a folder now. :-)

If you decide this tweak isn't for you, run this command to undo the change:
REG DELETE "HKCR\Folder\shell\Play DVD with VLC" /f
