I'm trying to edit the tags (title, artist, year etc) of a .mkv file with VLC Player. I open the video and select Tools > Media information (or ctrl+i). Then I do the changes I want and click in Save metadata. The tag seems to be changed only for the current VLC Player session, because when I open the mkv proprieties window, I can see it is not updated.

Is this a VLC Player bug? Can anyone help me with this issue? Or show me a way to edit the video tags. I searched for it and only found tag editors for MP3 and other audio formats.
