I use these tools: DVDSanta to create DVDs from video files,  and SUPER(C)to convert any type of video format to other format, and to convert DVDs to your computer as avi, mpg etc I use Cucusoft converter. If you convert a DVD to avi or mpg or vcd with cucusoft to your computer, you can use SUPER (C) to convert it to a smaller size in different format like xvid such as I explain in this video.Just google Cucusoft and DVD Santa if you have need for those.
