In fact, what I am using is just the popular DVD Ripper program: Pavtube DVD Ripper now.
It is used to convert DVD to many other video and audio formats, such as AVI, MPEG, WMV, MOV, MP4, MP3 compatible with iPod, iPhone, PSP, Zune.
I prefer the progam as its after-sale service is good. Last month, I encountered a problem and sent it to them, they replied and solved my problem on time.
So I think when choosing an appropriate program for ourselves, we should consider not only its quality, functions, but also its after-sale service.

I has tried some DVD ripper soft, But I like this software best, On one hand£¬It is very easy to use, and on the other, the function is powerful. I like it and If you are interested in this, you can have a try.
