Importing music to iMovie
I am trying to add some music to a home movie. iMovie tells me that there are 731 files protected and unavailable, but I can still see most of my music collection in the Audio screen. It lets me add the music to the movie, but about 1 second into playing the section of movie with the audio overlay, the sound wave image disappears and the music stops. Is this because it's allowing me to import protected music, or is this a different error? If it's because the music is protected, it would seem that my entire music library is protected, not just the 731 songs suggested, as I can't find anything that will play.
