There is only one video overlay and it can only be used on one crtc at a time (either the internal panel or the external monitor). In dualhead mode the overlay will follow the video window. In clone mode you have to choose one head or the other using the XV_CRTC attribute.

crtc 1:
xvattr -a XV_CRTC -v 1

crtc 0:
xvattr -a XV_CRTC -v 0
