Little bit of off topic, but if you want to burn mp3s to CDs, try:
http://www.musicmatch.com/
Musicmatch MP3 Jukebox. You can play MP3s in your computer, you can burn CDs - real CDs and MP3 Cds - it will change your MP3s back to .wav and burn you a CD.
Basic version is free. Burning version is paid, but cheap.
I have use it years.
Once my wife wanted to play old Beatles songs in car. Our Alfa Romeo have normal CD player. She choosed the songs she wanted (they were MP3s), burned normal CD and played it in car. Easy.
