hardware development is as good as not existant when it comes to beat DVD-Copy-Protections...
When the CD standard was created copy protections were not considered yet, letting CD recorder manufacturers implement things like RAW mode into their drives. When DVD recording was born, specifications took it into consideration as you may find even in some official documents (ECMA and probably others) things like :
17.11.3 Content provider information

received from the host be recorded in this field. Circumvention: Recorders and
recording drives shall be considered as circumvention devices when these are
produced to record, or can easily be modified to record, in any manner, a
user-defined number in this field.
