Public bug reported: When compiz is window manager, xfce4 panel covers mythtv video playback. I have tested with metacity and the problem does not occur there. Gnome panel / unity etc do not cover mythtv either, when using compiz. (they used to, but it appears to have been fixed.)
Most likely xfce4-panel is not setting some WM hint which is needed for compiz to know that fullscreen windows should cover it.
