Choosing a Phonon backend

[Tanguy Krotoff]

It's possible to add Qt plugins to its app by copying the *.dll/*.so
inside i_don't_remember_the_name_of_the_directory

But still, Qt checks first for QTDIR/plugins/phonon_backend so you
might end up with phonon_ds9 if you have installed the complete Qt
version. Of course for an end user, no problem.

btw, I checked Dragon Player source code quickly and you use sometimes
directly xine.h, why is that?
