White squares on videos I download

[Hunter's Torn Quad]

Sometimes when I download videos, usually music videos, they have a square pattern of these little white squares moving around the picture. They sometimes appear to fade in and out as they move around, and don't move in any particular pattern. What are they ? And can they be removed ?

maybe its a video card or monitor problem

 

or maybe your framerate settings

 

what speed do you click on when you download videos?

Maybe its a resolution problem. Look for higher resolution videos.
