I'm getting a message from iDVD 5 that "Your Macintosh does not have a supported SuperDrive. Please note that while you will be able to work with iDVD projects, you will not be able to burn a DVD Disc". My DVD drive is the Pioneer DVD-RW DVR-109. Any idea how I can get iDVD to support this drive? Has anyone else run into this? Thanks. Ron in Memphis
