problem with burning audio cd

I recently purchased a Macbook 2.13 GHz Intel Core 2 Duo. I've tried to burn audio cd's from mp3 in Itunes to use in my car but when I try them in the car cd player they don't work. But they work on my mac. I used to be able to do this on my old mac mini with no problems. I'm running the latest version of OS X. Anyone have any ideas?

And thanks in advance for the help.

Thanks for replying. Yes, definitely selected audio cd. Even reduced the burn speed. Didn't make a difference.

Using exactly the same discs. Tried converting the mp3's to aiff files and burning onto disc without Itunes, but same result.

I upgraded to Itunes 9.0.3 today and tried again. No luck. Same problem. I appreciate the help.
