The projector was temperoly located in the yard of Highland Park, can play video like game start video, full screen, can not stop.
The sample video are three MVs,
   Loving of Kangmei, Zoo Topia and AOA Miniskirt.
The video was put in the dir data\video, use the in-game bik format, convert with RAtools.
Here are the scripts used for playing:
   
 Scriptname DVHPProjectorControlPanel extends ObjectReference 
{ObjectReference}
Message property DVHPProjectorControlMessage Auto
Event OnActivate(ObjectReference akActionRef) 
int ibutton = DVHPProjectorControlMessage.Show()  
   If (ibutton == 0)
   Game.PlayBink("film1.bik")
    elseif (ibutton == 1)
   Game.PlayBink("film2.bik")
    elseif (ibutton == 2)
   Game.PlayBink("film3.bik")
    elseif (ibutton ==3)
   return                               
  endif 
endEvent

with messagebox in the pictures, anybody can edit it without permission, just a projector model, an activator and a script with prepared films, and can seperate out.

----------update 2
Use this update， should rename the old film name in the data\video,or the old file can not be played.
film1.bik rename to Love of KM.bik
film2.bik rename to ZooTopia.bik
film3.bik rename to MiniSkirt.bik

In this update, add three sample video from 4K demo, but after converted to BIK, the video effect is still so so.
Edit the esp and script, now point to the projector, the film name will show.


-------------Great news，from Chines 9dm commity, friend had test out how to stop playing:

  Alt+Tab Go out to desktop, will Stop the Playing
 Go back to Game, can choose film again.
