Why do you want to convert low quality MP3's back to the higher quality CD format?
I - Car
If you are trying to hear these in your car, you should get something like an iPod... or a car stereo that
can play
data CD's with MP3's...
(Or you can buy a Mazda Protege 3 MP3.
)
II - Home
If you are trying to play they on a home stereo, just go to Radio Shack to get a cable to connect the
mini-plug Audio out of your Mac to the dual RCA inputs on your stereo.
If you really really really want to burn MP3's onto an
audio CD, iTunes will do that... But you'll have poor sound and only fit the normal 70 minutes of music.
If I'm missing the point entirely you'll have to give us more info on what you are really trying to do. (i.e. I think the CD thing is your proposed
solution, but you should tell us what the
problem is...)
