How to convert DVDs to MPG

Recently I have some problem, I have some great DVD movie, but I need to tweak it. I want convert my DVD to MPG, because I need to edit with my video editor. Like we all know DVD format(VOB) is cannot directly edited, So I need to convert it.

After googling fro a while, I found some solutions from some forums. So, all we need is download some tools, there are a lot of free tools and this is some of them:

Smartripper (free, also built-in ripping)
DVDDecrypter (free, also built-in ripping)
Rejig (free)
VOBEdit (free)

And my favorites is VOBEdit, simple and powerful. All need to do just download and install, after install just select directory that contains VOB files and select destinations directory and thats all
