xna - Playing a Video (MSDN Tutorial) -

-

when trying example on http://msdn.microsoft.com/en-us/library/dd904198(v=xnagamestudio.40).aspx program crashes on

line 69: "player.play(video);"

error message: "an unhandled exception of type 'system.invalidoperationexception' occurred in microsoft.xna.framework.dll

additional information: unexpected error has occurred."

i did not change single character in code, used files came out of videoplayback_4_0.zip folder. (can directly downloaded http://msdn.microsoft.com/en-us/library/dd904198(v=xnagamestudio.40).aspx)

i have read in other forums people experiencing same problem, not find usable solution. know causes problem , how fix it?
