Video stimuli not resetting to beginning in online experiment

Maybe try this post for a specific fix for Chrome:

I solved similar problems I had when playing videos for a second time by combining some of the approaches mentioned in this thread and in others:

End Routine

myMovie.stop();
myMovie.seek(0);

Begin Routine
(the one supposed to play the video for the second time)

myMovie._movie.currentTime = 0;
myMovie.play();
