Culprit 1:
gui_update_cb() in totem.c
Only updates the volume to match what's in the backend. We should use property notifies and clean it up a bit

Culprit 2:
bacon_video_widget_tick_send() in bacon-video-widget-xine.c
We should disable it when we close the files, and restart when we open a new one.

Probably need to figure out how to avoid wake ups when paused as well, in both the GStreamer and the xine-lib backends.

Culprit 1 is dead.

        Don't run the ticks when paused or stopped,
