Your laptop has intel 915gm graphics, and intel hasn't released a driver for it since XP and has stated they won't be making any more because of it's age, so you're out of luck unfortunately.
If thats the case what a bummer. Its and old laptop I got on Ebay but it serves its purpose for where and how I use it. So its not the end of the world if no one else comes up with any other ideas.
try to install silverlight and watch it from a web browser rather than the app! i had a similar problem. seems to work! although a bit scippy! i think or its my eyes!
