"It allows to copy DVDs without menus using dvdauthor, which, as the name suggests, is a tool that helps you create menus, buttons and chapters. K9Copy supports various video and audio codecs, including Xvid, x264, WMV 7 and 8, RealVideo, MP3, AC3 or AAC. It can be set to use either mencoder or ffmpeg for MPEG-4 encoding, allows 2-pass encoding (which is slower but performs an improved, constant quality encoding), and it also allows you to select the size and number of output video files.
"...One of the nice things about K9Copy is that it also provides the option to extract only the audio, which can prove very useful for a concert/videos DVD for example."
