Someone already tested a homemade copy protection in DVD-R video based on:
CGMS (one copy is allowed) + DVD-RW CPRM media + DVD-R CPRM media? Quote:

Actually, there is a sort of a workaround here.
If youy burn your master to a DVD-RW that has a built-in CPRM system, then you will find that you can copy from the RW master, but you should not be able to copy the copy.
CPRM is like the SCMS system used by MiniDisc, and basically uses a scrambling system so that only a single generation of copies can be made. |

As most of new setop dvd recorders (from major brands) and dvd writers are CPRM compatible, the copy of DVD-R CPRM (with "copy of copy" not allowed) tends to be more difficult...
For the old BenQ DW-1620...
