The sitation: I've got a stack of audiobooks in MP3 format in my iTunes library, and both an iPhone and an iPod Nano.

After this question, I've changed the Media Kind for the audiobook MP3s from Music to Audiobook. This has been, overall, spectacular, as now I can resume where I was, they show up under Audiobooks, etc.

On the iPhone, it's also super convenient, since the interface shows what used to be an album with multiple songs as a single book with multiple chapters, and going into "Audiobooks" presents me with a list of books, not tracks.

The Nano, on the other hand, is a little strange. After changing the media type and re-syncing the ipod, the files in question are now listed under Audiobooks rather than Music, and the extra Audiobook features are present (resume playback and so on,) but the Audiobooks menu just lists all the MP3 tracks on the iPod in alphabetical order, ignoring whichever book/album they belong to - and doesn't seem to let me browse them any other way.

This is, clearly, a little sub-optimal. Did I screw something up? How do I get the Nano to treat the files in a similar way to the way the iPhone and iTunes does - as books with chapters?

Is there a step I missed somewhere? Do I need to reformat the iPod? Is this even possible?

(Footnote: shameless bump, since this just scored me a tumbleweed.)
