(Windows) iPod video conversion software?

I know this is probably not the appropriate place to be asking, but does anyone know of any good freeware Windows software for converting videos into iPod format?

Most of the videos are from my digital camera (Fuji S602)and have file names ending in .AVI

I searched google, with lots of results, some look a bit dodgy though. I was using the converter on this site: http://www.smallvideosoft.com/index.php But now it no longer works, despite claiming to be free.
