The video overlay only works on one crtc at a time.  In dualhead
configurations, the overlay will follow the window.  In clone mode you
have to pick which crtc you want to use the overlay with.  use a tool
like xvattr to switch the crtc used by the overlay.  Possible values:
-1 auto, 0 crtc0, 1, crtc1.

xvattr -a XV_CRTC -v 1
