Sometimes I'll get a 7 CD book which comes out on the SD card with 7 "Track one" files in a row, 7 "Track two" files, and so on. Then I have to go back and do them one at a time, but mostly it works just dandy.

I run across this as well. You don't notice it until you truy to rip it, but many audio books have inconsistant formatting of disc names and tracks. Its best to rip one CD to your hard drive, then manually fix any inconsistancies before ripping the next. I suspect these inconsistancies might be intentional to discourage ripping of an entire book to your computer, since nobody will ever notice if the book is just played in a regular CD player.
