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.
