  Hi Andrea,

  Your code is fine. It works for me with PsychoPy 1.76.00 on Kubuntu 12.04.

  From the PsychoPy group I read that avbin.dll generates some problems on 64 bit Windows machines, but as far as I know this problem should be solved now.

  From the error, it seems as though there is simply a bug somewhere in PsychoPy, not something related to avbin.dll (I think that would result in hard crashes, but I'm not a 100% sure). What version of PsychoPy do you use? In OpenSesame you can check this by typing modules() in the debug window. If you are up-to-date and still get this error, it might be worthwhile posting it on the PsychoPy mailing list.

  Edit: It could also be that PsychoPy cannot find the file, or that it cannot handle the video format. It's quite often in PsychoPy that crashes are not dealt with gracefully and result in uninformative error messages.

  Cheers!

  Sebastiaan

  Hi Sebastiaan. You were right, the problem was due to something in the video format. It sounds strange, because my initial video was an uncompressed AVI. I re-created a compressed video and now it works.

  Btw, in order to make my initial code funcioning, it has to be added a loop, so:

  from psychopy import visual
  
  mov = visual.MovieStim(exp.window, 'C:/Users/Andrea/Desktop/Movie.avi')
  while mov.status != visual.FINISHED:
      mov.draw()
      exp.window.flip()
  

  Cheers,

  Andrea
