Easy CD-DA Converter is an amazing tool to compress lossless files, converting them into mp3/wma/ogg.
It can handle SHN, WMA, APE, MPE, FLAC, OGG, WAV, 3GP. MP4, etc.
But I suggest you not to convert lossless into mp3 (if you need to do that to use with your iPod, go ahead)
try mininova.org dude. and find a full working version of that software. Check it with an antivirus before installing it
