How to rip DVD to iPhone 4

Question:
Recently I got an iPhone 4 as my birthday present, and I have lots of DVDs on my computer, could I enjoy DVD videos on my new beautiful iPhone 4 or other portable devices such as iPad, iPod nano?
Answer:
You know, the Most DVDs are .vob format and most people can only watch their DVDs on DVD player and computers. The standard DVDs can not be supported by iPhone 4 or other popular portable devices, so you need a DVD ripper to rip DVD to iPhone 4 mp4 format or avi, mpeg4, h.264 popular video format. So today I wanted to share with you a third party DVD Ripper to solve the questions above, but the moderator deleted this crappy product, because I'm a spammer
