If you call dd without bs= parameter, the default of 512 is
assumed. This may not be correct for video DVDs. You could
try bs=1m, but I'm not sure what the correct block size for
DVDs is...

For copying them, I always felt comfortable with the vobcopy
tool (for reading), and growisofs -dvd-compat (for writing).
Both tools can be installed via ports or packages.

Just a side note: I don't think /usr/local is a good place
to store DVD images. Some path like /usr/home/dvds would be
good. The /usr/local subtree is "reserved" for locally installed
applications; see "man hier" for details.
