You need something like decss to decrypt the stream and
something like M2VRequantiser:

Maybe "mplayer -dumpstream dvd://1" would do to decrypt the stream.
However, you need to demultiplex it "mplayer -dumpvideo dvd://1",
because m2vrequantiser only works on plain mpeg2 video streams.
Then you could remultiplex it with mplex and use dvdauthor to create a
working dvd, but losing the menus.
If you don't want to lose the menus, then I _guess_ you'd have to
decrypt the vob's, extract the video stream, process and remultiplex it
into the vob's.  However I never tried it so far.
