Sorry… I should have been more specific. The .m4b files now appear as regular audio… that works great! When using an iTunes client .m4b files show up as “Audiobooks” when using the Search Bar (ctrl+shift+b). This currently this works for the .m4v files as “Videos”.
I use this function to keep my audiobook collection better organized since I am no longer limited to using one or two genres to categorize my books.
