I have windows vista. There is a short video clip that shows up on my windows medial player that I want to delete. I'm not sure how it got there to begin with, but I have a feeling it has to do w/ my teenage son.

So, when I click on the play button (at the bottom of my screen in the middle) this short clip shows up. It doesn't show as listed in the media library. It is almost like a pop up.

Any ideas of how to get rid of it? I'm not the most tech savvy.

Thank you for your help.
