Vista - Automatic Media Info Download

I am having a problem keeping my music collection free of unwanted album art files. I have all of my mp3 embedded with the album art that I want displayed. I have disabled automatic downloading of media information in both media center and media player. I haven't had too much time to see if these files will accumulate again but I think this will work.

My new problem is that I use the movie guide feature quite a bit just to pick 4-5 movies at a time to watch at a later date. Disabling the media downloads is keeping the movie covers from downloading in the movie guide. Does anyone know a work around that would keep media center from downloading music album art while treating the movie guide differently?
