I have been evaluating a ripping software "Ideal DVD to iPod Converter" per my co-worker's recommendation. I'm deeply impressed by its ease of use. I srongly recommend it to you. I believe you will love it as much as me.
I forgot to tell you that, I also met some issue on using it. When I contacted the support staffs, they provided me awesome assist. They're the best service team I have met before. Great job and excellent guys!
