The encryption used on dvd is specifically designed to prevent making a
copy. Seems to me that's what you're running in to here. The only way that I
know of to actually copy a dvd, whether to your hard drive or to another
disk is to use a ripper to extract it and make a copy of it.
Of course then you get in to legal issues.

I guess because the DVD player un-encrypts it ??

Yes, it was a small single layer DVD that was copied. But it did not
play, giving me the "encrypted" message.
