Running Phonon under Windows CE

Hi! I'm trying to run the music player from qt demos on a device using Windows CE. I compiled for Windows CE and placed in the directory the correct libraries. I placed in the same directory another one, named phonon_backend with the backend. Unfortunately, still the player is not playing anything. I tried to see what backends are available, but it seems no backend is available. Any idea why?
Thanks!

No one has been ever able to show some videos using Phonon under Windows CE?
