I have WMP 11 and about a month ago it started having some weird problem when playing "some" movies. It has little arrows all over the screen -> you can see the picture, but any movement in the film and the arrows increase. I don't reall know how to describe it, but I have some screen caps if anyone can help. This problem just started and some movies play fine while others don't... all different video types (mpg, wmv, avi, divx)
