Using MPV to play DVD movies

Beside VLC, very few dvd players have [access to all DVD movie options, namely menus](https://unix.stackexchange.com/a/239771/32012) , and mpv is not one of them, but I use mpv to access external subtitles with DVDs and have started to appreciate very much this very simple and light and yet very capable player, so that I would like to provide an answer on **how mpv might be used as main DVD player** in spite of (or maybe because) its very minimal GUI.
