Hello, I am having issues with my audio/video from my in computer laptop.  I am trying to make short videos using the pre installed movie maker (I have a gateway laptop with windows 8, purchased in April 2013).  I can record the video I want using the camera and it seems fine.  when I put it into the movie maker program the sound slows down and becomes out of sync with the video.  This happens even if I don't make any changes to the video.  When the video section starts the sound is okay, but the longer it runs the more the sound becomes out of sync.  how can I fix this?
