Importing a .MOV file NO SOUND

I am trying to import a movie I found on the web.
It is a quicktime movie.
I downloaded it, sounds fine - but when I import it into Flash MX or Flash MX2004 everything goes fine but when I try to play it… No audio.

I have tested this on several pc’s here at work opening a generated .exe file.

Any clue to why this is happening? :puzzled:
