I think Pavtube DVD to 3GP Converter is very good. I downloaded it by chance (I even have never heard of it) and it is pretty easy-to-use but the function is powerful. In addition, the beautiful interface is my favorite. I have downloaded some software about DVD conversion before; however, Pavtube is really cool for using and operating. Because of curiosity, I looked through its product web page, and it is just released in February. If you are interested in this, you can have a try.
