Music is working fine along with Music Videos, but when I recently purchased an audiobook and click on audiobooks in itunes it shows up. I synced and then went into my ipod on itunes and it showed up. but when I disconnect and try to find the book under audiobooks it doesnt show up. I can find it with all myother songs but it would be nice if it showed up under audiobooks since the menu is there. What am I doing wrong?
