Thanks for the solution,it rocks !
from the example in

http://pygstdocs.berlios.de/pygst-tutorial/webcam-viewer.html

I slightly changed by 

	def on_sync_message(self, bus, message):
		if message.structure is None:
			return
		message_name = message.structure.get_name()
		if message_name == "prepare-xwindow-id":
			# Assign the viewport
            # all this is needed to sync with the X server before giving the
            # x id to the sink
            gtk.gdk.threads_enter()
            gtk.gdk.display_get_default().sync()
			imagesink = message.src
			imagesink.set_property("force-aspect-ratio", True)
			imagesink.set_xwindow_id(self.videowidget.window.xid)
            gtk.gdk.threads_leave()

as the exmple dos not use a VideoWidget class.
