There's plenty I use Avidemux. http://news.softpedia.com/news/Convert-DVD-Video-to-AVI-with-Avidemux-54002.shtml Guide is a bit old - based on Avidemux 2.3.0 when 2.4.4 is current version but it still holds. If it's a commercial DVD you need to strip the copy protection first. I use the free version of DVD Fab for this. http://www.dvdfab.com/mlink/download.php?g=DVDFAB5
