No, that's not good enough. You'd have to provide it with an actual,
valid key. This is not a go/no go check as you are trying to make it
appear.
The most important thing is that if these players require an Internet
connection for legal use, *nothing* will stop the need for them having
some kind of networking connection because there would be no other way
to get the changing keys to them. If you have a network connection
available for the player, it's quite likely you would have an Internet
connection, too, so why bother spending *years* to crack the system?
Yes, that's how long it will take...years. Because the request for the
disc key that is sent to the server would be encrypted with a public key
that *only* the server has the private key for. Then, the response
containing the disc key can be signed with that private key, which the
player will easily be able to verify (it has the public key).
So, if you can come up with the private key, hack your network so that all
requests to the real server go to your pirate server, figure out exactly
what twists and turns have been done to the encryption algorithm so that
you can package up responses that appear valid, keep up with all the
new disc keys on the global pirate server, keep that global server up and
running despite MPAA lawyers, yes, you will be able to watch movies
without connecting to the MPAA servers. But, you still won't be able
to copy them in perfect digital form.
