How do you make Windows Media Player the default?

I have Nero and Windows Media player. I like Nero but want Media Player as my default player. How do I do that so when I pop in a disk Media player runs it. I used to know ( I think) .

Go to WMP's Tools | Options | Formats menu dialog | Choose which file types you want WMP to be the default player for, then click apply...this dialog is at Tools | Options | "File Types" tab in MPXP and WMP 9 Series.

Thanks for the tip. I knew I had found it opnce before. Thanks again.
