SimpleMovieDemo() does not work on my machine!!

Hi everybody,

I am trying to see how Psychtoolbox presents an example .mov file. To this end, according to the following URL:
http://docs.psychtoolbox.org/SimpleMovieDemo

I simply entered the below function in the MATLAB command window:
SimpleMovieDemo;

but each time MATLAB returns a same error:

??? Error using ==> Screen
Usage:

[ moviePtr [duration] [fps] [width] [height] [count]
[aspectRatio]]=Screen('OpenMovie', windowPtr, moviefile [, async=0] [,
preloadSecs=1] [, specialFlags1=0][, pixelFormat=4][,
maxNumberThreads=-1]);

Error in ==> SimpleMovieDemo at 47
movie = Screen('OpenMovie', win, moviename)

I checked the existence of the default .mov file: it is still there!

I would be grateful if anybody can say what is probably going wrong?


Many Thanks in advance,
_V

PS: I use OS X.
Did you install gstreamer per instructions on the psychtoolbox wiki and did you UpdatePsychtoolbox()?
Best,
Dee
