#3230: Unable to import certain newer DVDs

When trying to import newer DVD releases, such as ''Stranger Than
Fiction'' there are a few problems:
(1) When showing the number of tracks available for import mythdvd reports
99 tracks available, which I doubt is correct. Several of the tracks have
the (seemingly) correct length of approximately 2 hours.
(2) When trying to rip at any other quality than "ISO," the progress
screen briefly comes up, and then quickly returns to the "hit 0 for new
import" screen
(3) When trying to rip at "ISO" quality, the rip continues for a couple of
minutes and writes between 700MB-800MB to the disk and then suddenly
crashes back to the "hit 0 for new import" screen.
I am imported several other DVDs successfully and the hard disk is not
close to being full. After looking into /var/log/messages on my system
(Gentoo), I saw these errors:

The DVD has no visible scratches on it. After doing some Googling, I found
other DVD rippers having similar problems. Please see:
http://forum.doom9.org/archive/index.php/t-123124.html
In summary, this seems to be some sort of purposeful-bad-block scheme, in
order to prevent users from creating copies of our own DVDs! I have seen
this problem on another DVD I own, but I can't be sure it is the same
thing...
