The encryption is completely intact.  MythTV does /not/ strip out any

Myth does not exist to copy encrypted DVD's, considering copying of
those DVD's is illegal in many parts of the world*.

*This statement assumes the DVD is an encrypted commercial DVD protected
by copyright.  Since I know of no means of encrypting a DVD without
obtaining a license for CSS from DVD-CCA, I'm assuming all encrypted
DVD's are commercial copyright-protected DVD's.  (After all, why would
anyone reverse engineer a means of implementing a broken encryption

IMHO, this is not the place to discuss copying DVD's.  (Note that I'm
not saying that it's possible nor that it's impossible to do what you
ask.  I truly have no idea because I've never made a copy of a
commercial copyrighted DVD that's protected by CSS, as, for me to do so
would be illegal because I live in the US.)
