Comment 22 for bug 600178

I think only way to play full screen video with no tearing in Natty, is to disable composite extension (see comment #15)
Then you need to use classic mode without visual effects (select in login screen).
I'm using nvidia 9400M with driver nvidia-current (270.41.06).
I tried also nvidia-173, but I could not get vdpau working on it.
Can any other nvidia driver to be get working with nutty? I tried several from NVIDIA, but seems those can't compiled or does not work with current X version.

In 10.04 with these settings enabled I had no tearing with full screen video:

Workarounds:
Legacy fullscreen support

General options:
Unredirect Fullscreen Windows
