I remember I have googled at lot to find a free audio/video converter since I didn’t feel it is (really) necessary to buy a paid software from amateurs only to find surprises!

So I finally found one which offers free stuff, Jodix.com

They have different tools for the job;

WMA to MP3 converter

RealMedia to MP3 converter

DVD MP3 Ripper

Free iPod Video Converter

All of them are free, go grab it :-)
