[PyQt] Phonon-VLC

[Timothy W. Grove]

While I'm experimenting I may have another go at using phonon. How do 
you set the backend to use? just by putting a phonon_backend directory 
in my program's folder?? The important thing for me is the ability to 
send extra commands to the vlc backend such as '--autocrop' or setting 
the playback rate. Can this be done through phonon?

Best regards,
Tim
