There are two different versions of ddrescue floating around:
GNU ddrescue:
http://www.gnu.org/software/ddrescue/ddrescue.html
Kurt's dd_rescue:
http://www.garloff.de/kurt/linux/ddrescue/
I used the GNU ddrescue for my script. For a "tough" DVD you might
try the following two pass method:
1) Get as much as you can first pass:
ddrescue --verbose --no-skip --block-size=2048 /dev/dvd /var/movies/
dvd/tgn.iso /var/tmp/tng_ddrescue.log
2) Test it out. If it plays fine then you're done.
3) Second pass to attempt to get more data from the 'bad spots'
ddrescue --verbose --block-size=2048 /dev/dvd /var/movies/dvd/
tgn.iso /var/tmp/tng_ddrescue.log
Which DVD are you trying to copy? Is it damaged from scratches or is
it a Sony Pictures or Columbia Pictures DVD with ARccOS?
A bit more about my experience using the above method. Casino Royal
took 10hrs. I canceled the the second pass with about 100mb left and
had no issues playing the ISO file from xine. Silent Hill I let run
for 15hrs. Not sure it's fully copied yet as I haven't played it.
There were some others I don't recall off the top of my head that had
ARccOS on them that I've had copied in 3-4hrs.
So yeah, it's time consuming. If you want the whole ISO it seems like
the way to go though. On the other hand, if you just want the main
movie you can use something like mplayer or vlc to save the output
stream as it plays.

Hope this helps.
