Help! i just upgraded to windows 7 and reinstalled a clean copy of boxee. i linked my media sources, and it has scanned them all, the problem is about 60% of my TV shows are missing any form of cover art. in place i get gray pictures of a video camera.... i have tried removing the sources and re adding them, i have had boxee running for about 24 hours and it has not resolved it on its own, i have restarted several times, and there is no change. can someone please help me?
