Steve,
I use LimeWire to download files. We Mac users don't really have much more of a choice.

Can you still use your version of Toast with your new CD burner? Didn't your new one come with any software? Are all the mp3's corrupt? Is that why you can't burn them?

Wow, I didn't know it was $90. I got a discount because I registered my free version. But, I figured it was worth it because I have made alot of CD's and a couple of videos.

Hmmm... maybe you should see if sprinklerman's ideas will help. Good luck.
