Coverting from vob to wmv, avi etc?

Sorry for this real newbe question. I have a dvd of a friends wedding. It was recorded from VHS to DVD using a dvd recorder. So now I have a dvd with VOB files like a normal dvd movie has. I want to capture a small clip from this dvd and save it as a wmv or avi or mpg etc. How do I do this? Is there a free program to download etc?

Take a look at . There are numerous program links, guides, and tutorials.
