To rip mp3's you need a mp3 encoder. Get lame here.

.ogg will not play on a cd player. To play on a cd player they will have to be .wav.
Or if you have a player that plays mp3 from cd then they will have to be .mp3.
After installing Lame, choose Lame encoder in grip to rip with, and you'll get mp3's.
good luck
