Jodix Free Ipod Converter

I have a lot of files in the avi format that I want to watch on my iphone and ipod touch.  Most of these are DVDs that I ripped to my computer.  I need to convert them to an ipod format like mp4.  I had purchased a Xilisoft product to do this but it had expired and was not that great.  Before buying the newest version,  I downloaded Jodix Free Ipod Converter.  Its perfect.  It keeps the audio and video together and takes up few system resources.  It is also free.
