Yes, get a file converter. there are hundreds of free ones out there. go to download.com and search for em! I use a video converter for those irritating DivX files, and will occasionally switch them to an acceptable iPod format (although, I'm at a point where I'm about to get rid of my Pod for a Zune).
From a quick search, I did find this one
http://download.cnet.com/JetAudio-Basic/3000-2141_4-10013740.html?tag=mncol and from the quick skim I did, ot seems like it'll do what you need.
I hope this helps!
