I had this problem with the RC and I had hoped it would stop when the final version came out, but no luck. I subscribe to several podcasts through Itunes and purchase music from Amazon, which all show up just fine in their respective folders in the Music folder and library. At first, WMP would update the library after downloading new material, but eventually it stopped updating. When I try "apply media information changes", it scans the library, but finds nothing new. I'm stumped, and open to the possibility that I did something stupid. Any ideas?
