I have had the same problem, with my system. However from reaseaching the solution, I have found that the codec being used to play the video, is what causes the video to do what it does. check if you codec software has some kind of option to turn off the mouse. I am working on a commerical software so I really cant go into detail but. you can (depending on what programming language you are using) Use the windows API calls the capture mouse clicks outside your form and respond to them how you see fit.
