Playing video files- sound only

Hey all,
I just transferred my experiment to the computers we'll be using in my lab to run my experiment. Everything was running perfectly on the main computer (the one I used to create the experiment files), including the videos. However, now that I have set everything up on our experimental computers, when it comes to viewing my stimuli video you can hear everything but the video itself does not show up--you can't see anything. I have specified the correct files paths and everything, and my videos played perfectly on my main computer. They are .avi files, which are supported by MediaLab, so I am very confused as to what I can do to get my visuals going with the sound.
