Hi Jean,

Yes, I did remove the DirectShow dll. The only DLL in the phonon_backend
folder is phonon_vlc.dll:

I also copied the plugins folder. What's is strange to me is that, even if
 the library has been remove (phonon_dsp9.dll) I can see references to it
when profiling the app through DependencyWalker.

I must be missing something obvious here, but I just don't know what :(.
