I do not know if and explained well, but here goes.
I'm looking for some spoiler or tell me I should change so that when you close a spoiler that contains a video or an MP3 player such that it stops, ie stops working.
I leave here an example of what I want:
http://www.laps3.com/foro/93_trofeos..._colossus.html
search: VALUS, MINOTAURUS COLOSSUS (1 st spoiler down)
As you will see if you get to play video and then close the spoiler this video will stop.
Thanks
