stopping a movie

I have not received an answer to a question I posted on the 18th. I am getting close to starting my experiment and hopefully I can get a response soon

I have a file in which a 60s video plays. I want to take rt to the movie and have it stop when participants press the space bar and then go to a text box. it will take rt to the movie, but then the movie continues with the text box on top of it. I even tried to insert a blank screen between the 2 stimuli (movie and text box) and the movie starts playing again. I dont think i have specified this..... my csv file is attached to my other posting.
