Try chopping the problem in half. Download a free m4b from Naxos and see if
that works in your set up. If your m4b is not too big and not too private
dropbox it somewhere and I'll have a go at it.
Wikipedia topic "MPEG-4 Part 14" explains the whole sorry mess. The guts of
it is that the m4b is the same as m4a. They are both container formats so any
approved codec within has to be dealt with by the audio software. That might
be where Fission is tripping up for you and not for the file I tried it on.
The same article names m4p as an extension for protected files. It was used
by iTunes in the bad old 'Fair Play' days.
