Question about movie making in MTV Virtual Worlds

I have a question for anyone who has been playing around in MTV's Virtual Worlds. I have been recording video in this program but I cannot figure out (if I can) how to get rid of the word bubbles that come out of everybody's mouth. I know that you have to hold down the Control button during recording to get rid of the control panel at the bottom but it is no such luck with the bubbles. I find they can be distracting when playing back the video clips. I welcome any suggestions. Thanks so much!!!
