Correct.  If you use dd to copy an encrypted disk, the result will be
missing something like 90% of the data.

No it doesn't.  You can use dvdbackup (or k9copy or ...) to copy the
DVDs to the computer and when you play them back you get all the menus
and special features and whatnot.  If you want you can create ISO
images and burn them to dual-layer-DVDs, but you don't need to do that
to play them with all the features.
