So the answer is to boycott Matsushita drives, and only use 'open'
ones...<br>

There is actually some probably-fertile ground in there for big lawsuits
from the DVD consortium against the DVD drive vendors that did not
encrypt and sign the firmware (so that modding it requires JTAG access
to the drive uC or a lot of crypto work that is too dificult (or too
much of a bother) for the RPC-1 firmware scene), nor enforced RPC on the
data transfer layer.  AFAIK, Matsushita is the only vendor which does
*both*.

So, don't expect any vendors with easily-crackable DVD firmware to ever
speak about it... which is pretty much everyone else.  Certainly, one
can seem to find RPC-1 firmware hacks for just about every other DVD
drive vendor than Matsushita.
