What can i use to convert flv files to dvd format for free with no watermark?

downloaded a download flv movie that came in flv format but i want to make it into Dvd format so i can burn it on a DVD-R disc and watch it at home. DVDflick is a nice free dvd burning software without any limitation and watermark, and here is a guide about how to download and use it I'd prefer using this all-in-one dvd creator, my friends recommend it to me, it's not free, but it's easy to use and works pretty well, I think it worth the money.
