Open windows media player and click on the tab at the top marked "Burn". When the burn page opens click on the tab just below marked "Edit playlist". when the box opens navigate to the files you want to burn to cd and select single or multiple files to add to your cd burn, a single click on a file will put it into the right hand box. When you have put all the files you want to burn in (keep an eye on the total time at the bottom right, you have 80 minutes recording time on a 700Mb disc) click on "OK" and then click on "Start Burn", windows will then burn your disc for you. Make sure you have a blank cd inserted when you do this.
