vobcopy called without arguments will find the mounted dvd and copy the
title with the most chapters to the current working directory (thats the
directory you're invoking vobcopy from). It will merge together the
sub-vobs of each title-vob (vts_xx_yy.vob => the xx is the title-vob,
the yy and friends are the sub-vobs, mostly of 1 GB size) and copy them
to harddisk in 2 GB chunks. It will get the title of the movie from the
dvd and copy the data to name-of-moviexx-1.vob, name-of-moviexx-2.vob
(the xx being the title number). Also possible is to mirror the whole video
dvd content and single files can also be copied.
