I had some duplicate movies showing in WMC so I went through the steps that I found online to delete the cache and they were still showing. So I removed all the folders from all the libraries and deleted the cache again. Now all of my libraries in WMC except movies are empty. in Movies I have 64 movies left (I think they were all the duplicates). How can I get rid of these?? I checked WMP and it's movies list is empty (they use the same libraries don't they?). I've cleared any caches I can find DVDinfo cache, artwork cache. Rebooted. They still persist.
