Want to watch the movie on my iPhone with good quality?

It seems so funny that I have also watched DVD movies on the dvd player more than one years. However, when I try to transfer some dvd movies onto my iPhone option, things went not quite well. I want to watch some classic movies on iPhone at fast speed and with high quality whenever I like. But everything seems so difficult. How can I transfer them quite well?

Never expect to transfer any dvd movie to your iphone directly with copy and paste. It is just useless. Most moment, dvd movies will have copyright protection and not allowed you this action. Some dvd ripping software may have the abilty to remove the protection. So you know what you really need.
