dvd ripping linux

Here's how to rip the entire DVD:

dvdbackup -i /dev/dvd -o ~ -M

That puts the DVD contents into a new subdirectory of your home directory (~). To then generate an .iso, use this command:

mkisofs -dvd-video -udf -o ~/dvd.iso ~/[movie_name]

If you want, you can alternatively only rip the main feature (see archlinux or sourceforge documentation). If you want a video file (e.g. .m4v) instead of an .iso, use handbrake after ripping the entire DVD (don't forget to install libdvdcss!).
