I need this matinee video and menu to appear once!

I have a main menu screen that pops up after a matinee video is played, but i have 3 problems…

  1. Matinee plays over again and again whenever i click the play game button
  2. Main Menu will not go away on actor remove from parent
  3. matinee can play in my level without me having any blueprints attached to it(simple play and reference to matinee with all links broken+compiled
