Default Re: tearing with vdpau on multi-monitor setup

Unfortunately, there does not seem to be a similar "Sync to this device option:" for the vdpau video adapter (and neither for OpenGL, by the way).

Is there a way to control which display device the vdpau video output syncs to, so I can get tearing-free video on an external monitor?
I got vdpau tearing on 1 monitor on all 3 computers i use. So i disabled the composite extension in xorg.conf and all is well, no more tearing. Also, no Compiz or other composite-using programs will run this way.
