Hey Kevin, firstly I have not seen this problem before. But, in the absence of a solution from our well paid MS, here is a crack at some help. Any help is good help - right?
Question: Have you upgraded your video card driver lately?
If you have, then I recommend you re-install WMP or its codecs.
Let me know how you get on.
