I've read you MacWorld article. I often purchase audio books on CD from Amazon (pretty cheap.) When you look at the files the publisher has intentionally changed the chapter titles and headings to make it difficult to manually reorder the chapters after ripping. iTunes has a great way of automatically placing the chapters in order when the files are selected and organized as audio book so they are heard in proper sequence. Since every book i've ripped has a different type and alphabetic arrangement (no discernible pattern) for chapter listing there must be some outside mechanism for sequencing the chapters not obvious to the end user. How does it do this?
