Thank you for the reply! I’m sorry for the slow response; it took me a while to get back to this. I tried the suggestions at that link, but it didn’t solve the issue in Chrome: movies would play for the specified time (which is slightly less than the full movie duration) on the first presentation, play the final few frames on the second presentation (without resetting to the beginning of the movie, which was the problem), play from the start and appear correct on the next presentation, and so on.
I finally added the line movie_stim._movie.currentTime = 0; to the Begin Routine section of the JS code that plays the movie; this seems to have solved the problem, just in case anyone else runs into the same thing.
