I found out my problem and can now distribute my phonon based program.
It was very simple in the end :)

According to this: http://doc.trolltech.com/4.4/plugins-howto.html
dynamic plugin dlls need to be stored under their parent directory - e.g.
phonon_backend/
I had tried storing them in plugins/phonon_backend/ and bin/ but neither
worked.

Hope that helps someone else,
Richard
