Copy everything from a dvd to harddrive using dd
DVD Copying to hard drive with dd
In adddition to using vobcopy, and mkisofs you could also use plain old dd to do the trick ( sometimes )
It sometimes works, and when it does it works well.
From the command line in *nix ( Unix, Linux, OS X, etc. )
> dd if=/dev/dvd of=/tmp/dvdfilenametocreate
Lets break this down. dd is the command you are running, and if is the input file, everything is a file in *nix, and of is the output file you wish to write.
To find out more about the dd command you can check the man pages.
Thats it.
Simple and to the point. This will work for only some of the dvds you wish to make a backup of.
Commercial DVDs will need some other stuff to make it work.
Take a look at vobcopy and mkisofs if dd doesn’t work.
