Control quicktime video loading external with lingo

Question

Hello:
I have a director 11.5 movie in wich I need to show several quicktime videos. When the user click button  one (5 buttons) the video 1 plays. Is possible in the same Director movie to loadthe requested video changing the cast or sprite in fly?
can you tell me how, please?
Thank you very much.

You can swap video sprites on the fly, just like images. If you had "video1" and "video2" in your cast, and sprite channel 1 was video1 you could do something like this:
on mouseUp me
  myVideo = sprite(me.spriteNum).member.name
  if myVideo = "video1" then
     myVideo = "video2"
  else
    myVideo = "video1"
  end if
  sprite(me.spriteNum).member = myVideo
end
If you have a lot of videos you could handle them like this:
property pMyList, pNum
on beginSprite me
  pMyList = ["video1", "video2", "video3", "video4"]
  pNum = 1
end
on mouseUp me
  -- increment list value
  pNum = pNum + 1
  if pNum > pMyList.count then
    pNum = 1
  end if
  myVideo = sprite(me.spriteNum).member.name
  -- use list element to determine which cast member to display
  sprite(me.spriteNum).member = pMyList[pNum]
end
