// that is, the UI is embedded in the video stream rather than the stream being embedded in the UI.
// as a consequence, buttons and menus can asynchronously pop up out of the video stream source(dvd navigator)
// and, may require the focus. this inside out paradigm is the only situation where
// getfocus should be used. otherwise, weird non-standard interactions will result.
