Yes your card has it.
All 7xxx have it Id bet and prolly the newer 6xxx have it.
Its basically like it uses aa and stuff on video..
So for instance on my computer screen at resolution 1600x1200 it has the smoothness of being at 800x600.
It works too cus in VLC player you can choose to use the video rendering/hardware rendering or w/e and you can notice the difference in family guy.
Like it looks like crap fullscreen at 1600x1200 but with the rendering hardware thing on it looks like dvd quality almost.
There are prolly other functions too but basically it makes video look better.http://www.pcper.com/article.php?aid=102

There is software tho it only works for wmp and media center.
And you gotta pay so its not that cool.
I havent tested out the software yet but I will soon.
Dont really need it either, the hardware is enough.
