How to get music CD to Autostart again?

Experts,

I had to do this once a few years ago. but I can't remember how:

Windows 2000 laptop.  I want Windows media player to autostart when a music CD is inserted. Mindows media IS the default player because  it starts when i right-click on the cd in My computer and choose PLay.  But how do I get it to start playing automatically.

I re-installed Windows media Palyer 9 thinking that might get it back. But no.

Thanks
