This may be because of new forms of copy protection they are adding to
DVDs. A DVD player navigates through the disc based on the structures
in the VOB files, so it can be told to skip blocks on the disc. If you
try to read the disc as a UDF filesystem, you'll hit the blocks that
the VOB navigation skips.
The copy protection works by making those blocks bad so you cannot do a
block by block copy of the disc.

If you get a recent version of vobcopy (http://vobcopy.org/), it should
be able to make a copy of the disc which can then be played off the HDD.
