Copying a DVD for a client

Hey Guys,
Hope thi sis the right place to ask…

I have a client whose product is featured on some video footage on a DVD. They want this adding to there site.

I’ve got no problems incoding from one format to another but I’ve never copied a DVD. There seems to be a multiude of applicaitons out there for dooing so…can any one recommend one thats easy and straight forward to use?
