I wanted to build something to catalogue my audiobooks. I opened the starter solution for content management. If I drop an m4a into the content manager db, it pulls title, author, etc. straight from the file and displays a thumbnail of the cover. It doesn't do that for m4b. I'm not sure why; but think if I could just get it to identify m4b appropriatley, that I could use the starter solution with very little modification. Any ideas on how to get it to recognize m4b?
