Well, I just checked and after switching to external player, and selecting a movie and hitting play, it does give me a popup/selection window at the bottom to be able to select one of my installed external players (like I mentioned, I have VLC/MX and HB installed) so I have a choice. If I select "just once" when I choose, it will ask me every time. If I select "always" then it will no longer ask me, and launch the external player automatically. Since I do a lot of testing of different media, I typically select "just once", so if a player has issues, I can easily select another player and try again.
