Radeons only have one overlay so you can only have it on one crtc at a
time.  in clone mode you'll need to set the XV_SWITCH_CRT attribute to
1 to switch the overlay to crtc2 in clone mode.  you'll need an app
like xvattr to switch the attribute. in dualhead modes the overlay
will switch based on which head the video is on.
