use the freeware version BEFORE buying anything.. see if it does what you want beforehand.
i did a google search for "dvd to flv free" ( without quotes) and a top result was this one
Code:
http://www.winxdvd.com/free-dvd-to-flv/
Try it see if it does what you want THEN go buy the updated version afterwards.
