DVDFlick is a conversion program for dvds. It will convert various types of video to dvd-video format, but it does the actual burn to the disk with ImgBurn.
If you want a similar program, look at AVStoDVD. It is free to use and in my opinion, can produce slightly better results using the HC encoder that is included. AVStoDVD can also use ImgBurn for automatic burning to the disk. http://sourceforge.net/projects/avstodvd/
