Summary
a) If you focus on the conversion speed and the cost, Wondershare DVD to iPhone Ripper is the best choice. It can also convert DVD movies for iPod and Apple TV and this three-in-one function could save me about a hundred bucks.
b) If video and audio quality is your first concern, I would recommend Wondershare DVD to iPhone Ripper and Aimersoft DVD to iPhone Converter.
c) If you just want the easiest-to-use program, Kikee DVD to iPhone Converter is a very good choice.
d) If you want to rip two DVD movies into one file, the only choice is Lenogo DVD to iPhone Converter.

The above is my experience with iPhone converters so far. And I hope it can help iPhone users like me to select the right conversion tools. Open to discussion and more recommendations.
