If you are trying to go straight from a protected dvd, Handbrake will not break encryption…not on Windows.
On a Mac you need VLC installed, and on Linux you need libdecss to break encryption, and even then, it will not work on dvds with advanced protection schemes.
So, on Windows you’ll need to decrypt and rip to the hard drive first. DVDFab HD Decrypter can do this for free. With little information to go on, I"m just guessing that you are trying to copy from a commercially made dvd though… so if not, let us know.
By the way, I’ve merged your two threads. No need to start another on the same subject.
