vobcopy without any options will copy the title with the most chapters into files of 2GB size into the current working directory.
-l, —large-file write data into one file (needs large file support (LFS))
-t, —name NAME you can give the file a name if you don't like the one from dvd. -t hallo will result in hallo.vob. (stdout or "-" are deprecated now) If you want to give it names like "Huh I like this movie", do it in quotation marks.
-m, —mirror mirrors the whole dvd to harddisk. It will create a directory named after the dvd and copy the ifo, bup and vob files there. The title-vobs are decrypted during this.

Run vobcopy. It will automagically copy all VOBs that belong to the title with the most chapters onto your hard disk.
This will copy the VOBs from the DVD and write them to the current directory (which you can alter with e.g. -o /space). They will be named after the DVD's title (e.g. I have ALLY_MCBEAL_DISC21-1.vob, ALLY_MCBEAL_DISC21-2.vob etc.). The -m switch causes vobcopy to actually mirror the DVD's contents including the .IFO files - useful because you can then use the local copy with MPlayer/MEncoder or transcode just like it was a real DVD. It will take some time. Just be patient.
Note from the author (Robos): vobcopy has some problems following angles. You might get duplicate scenes with e.g. "The Matrix". I'm working on it.
Another note from Robos: There's another new utility called dvdbackup that can also copy DVDs.
