PB titanium + encrypted DVDs + Jaguar

[Simen Timian Thoresen]

I may be wrong here, but my impression was that it was /impossible/ to 
decode a zone X disk on a drive locked to zone Y, as the drive itself does part 
of the decoding. RPC 1 or RPC 2 only handles how this locking is performed, 
an if the drive is allowed to defer lock management to the application in case 
the drive is not yet locked.
