Converting WMA to MP3?

I'm not good with computers. I'm not terrible, but don't be too technical. I want to make some MP3 Cds for my moms stereo but all my music is ripped from cds in WMA. I love WMA so i wanted to see if i could convert the files to mp3 and then burn them and erase them. In WM player i can rip my cds in mp3 format but i cannot convert the wma files to mp3 in the WM audio converter. I need a codec, aparently. My questions are:


If i can rip the CDs directly to MP3 format, doesn't taht mean i already have the codec?


Where can i get a codec? can you recomend one? i'd prefer a free one, but i'd rather buy one than downloading som crappy thing that will damage my computer....





Thanks

Converting WMA to MP3?
It'd be easer to use a free or trial program that converts .wma files to .mp3 files because they usually have the codeces needed already installed. Here's a list of some but be careful because I haven't used them and therefore can't recommend them.
