iPod New Sections Under Library Tab

I know of no way to create more, but if you get any audiobooks they automatically become a new one named "audiobooks" and with a little book icon. On that note, does anyone know why two of my three audiobooks are under this "audiobook" category and one is under my music library? Any way to change this? (I don't mean to jack the thread...)

*Edit*
I think something that would suit you better would be to change all your movie trailers to "tv shows" and then make them all the same show, say for example "Movie Trailers" as the show name. That way they are all organized. I do this with my video clips and it works out well.
