I am afraid that you have to wait until Keith or Eric fixes this issue as
Intel did not release the documentation. I do not know whether video overlay
for G965 is not supported due to HW limitation of G965 or by temporarily 
non-working overlay code.

Btw, I can also see tearing during playback. If I remember correctly, Keith
said that tearless video will be available after DRI rework.

I wonder why legacy overlay is not working at least on i915 which is capable
of video overlays.
