what I am using is 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.
Moreover, it's the cheapest I have ever found.
