I have 6 Harry Potter books that were given to me in mp3 format. I used db poweramp to convert them to m4b. But, when I import them into iTunes they just go to the music option and the mp3 files disappear out of the folder I put them in. Y and how do I fix it? OR...... Is there a program out there that does everything iTunes does except erase my iPod. I have a new 160gb classic. thanks.
