I'm confused. If you could please provide details, as to what exactly is going on, we can help you. Stuff like the blank media (Media ID), specific fab application and version, burner, movies that you're trying to copy (include region), etc., etc.
When you said, "... when I go to run then I a error massage Disk is not formated...", are you trying to view the disc directly by clicking on the run command in windows?... You need software to watch a disc, like Power dvd, Intervideo Windvd, Nero showtime, etc.
