I'm also trying to solve the tearing issue. I tried Mandriva 2009 on my machine and it doesn't suffer from tearing. So, I guess is not my hardware, but Ubuntu itself.
EDIT: I finally solved the problem on my machine by enabling "Unredirect Fullscreen Windows" under CCSM General options

The problem exists with or without compiz. It is a driver issue.
I have found a solution that works temporarily.
You have to use VLC, and set it to use xVideo, and in the settings xVideo has an option of -1, set it to 1 and it works without tearing.
But the problem still remains everywhere else. I'm hoping a solution comes fast!
There is no video tearing at all if you have your compiz config manager fixed properly...well in my case, it runs fine.
HERE IS THE DEAL
in compizconfig settings manager, you must use these settings.
Texture Filter "best" if you have it fast, video tears.
detect refresh rate "OFF"
Refresh rate "200"
sync to vblank "on"
detect outputs "on"
remove all outputs.
overlapping output "smart mode"
anyway, keep your texture filter at best since this greatly affects the video refresh and tearing.
your other problem could be refresh rate is not correctly set for monitor.
