Well only for the time being. You're not a smartarse, but - it isn't 10 years old as I have checked.
However they (NVidia) did say they were supporting it in Vista and it works. And DirectX9 was introduced in December 2002.
So why does a card introduced in 2004 not work with Aero for DVD burning (which does a brilliant job) but one in 2003 does?
See the table below of the FX5200...

Don't ask why I did that.
