In making a CD recording of music in iTunes, there is a menu to select the correct format for what you are recording. Choices are Audio disk, MP3 and Data. I select MP3. The music "apparently" records but when played back on an MP3 player or a standard cd/DVD player, which plays any MP3 disk, there is nothing there. In looking into it, the DVD/.CD player identifies the disk as a data disk, which I think explains the playback problem. How to get i get iTunes to follow my instruction to use MP3 and not Data format"?
