You might be seeing fake files, these will sit connecting for ages & then get stuck needing sources...they won't ever download. Always check movies with Bitzi before download. Music doesn't get rated on Bitzi as much...search for artist or album name rather than song title. Use the All Types search. Stay away from popular files with huge numbers of sources...go for a file with 10 sources or less
