+ * Now as we currently do not show a QTKit control bar with scrubber for display sizes > container
+ * size, this seems to facilitate playback control from the HB custom HUD controller fairly close
+ * to the built in controller bar.
+ * Further work needs to be done to try to get accurate frame by frame playback display if we want it.
