1.If you use this hack two Zune icons may appear in Windows Explorer. To get rid of one of them go back to the regedit device parameters we edited before and look for \WpdMtpDriver\UseWpdPrivateInterface and change the value from “1” to “0”

2.Zune software needs to be open at all times. There is an authentication Mechanism and if you close it you can only view the contents of your Zune and not play them. By pressing the “Start Sync” in the Zune software, temporarily you get write access to files and folders during the sync. Just drag and drop files into their proper folders. Music, Video, or Pictures. Do not delete any files from the Zune root directory.
