Creating a single file, lossless rip of a DVD chapter in Ubuntu

Several options:

• Use k9copy to create a .mpg file, if you don't mind installing the KDE libraries.
• Use dvd::rip ("Rip selected title(s)/chapter(s)") or dvdbackup --feature, then cat *.vob > movie-name.mpg
• Use MakeMKV to create a .mkv file.
