[Aljosa Mohorovic]

i'm getting "the video widget could not be initialized correctly"
error, anybody knows what is causing this?

code:
-------------------------------------------
import sys
from PyQt4 import QtGui
from PyQt4.phonon import Phonon
from gui import Ui_MainWindow

app = QtGui.QApplication(sys.argv)
window = QtGui.QMainWindow()
ui = Ui_MainWindow()
ui.setupUi(window)

file = r'C:\movie.avi'

vw = Phonon.VideoWidget(ui.widget)

window.show()
sys.exit(app.exec_())
-------------------------------------------
