The following is an excerpt from an Audio Video Revolution Audio/Video News
article by Jerry Del Colliano dated March 8th:

"What they have done is built in code that can change the copy protection
scheme on the fly. DVD's copy protection scheme (40 bit encryption) has
long been broken but Blu-ray's 128 bit scheme is far harder to break. When
it is broken they reserve the option to change the copy protection on your
machine. You might not like it but you have little choice if you want to
watch movies in HD. That same connection can also add value to movies with
additional content, director's comments, deleted scenes and so on. Blu-ray
players do have some storage on them so that you can save additional
materials."

Based on Shane's comments the other day about the ability to dynamically
change the copy protection scheme, I've read a little bit about this
ability and this article explains the basics. The comment about "That same
connection can also add value to movies with additional content, director's
comments, deleted scenes and so on" to me is worthless. I personally could
care less about that capability. My question is that when the protection
is broken why wouldn't I simply disconnect my HD player from the
Internet/phone line and remove their ability to update my HD player? I
guess what the manufacturers could then do is encode any new HD DVDs with
an update code so that once it was inserted in the player that the new copy
protection scheme would be implemented. Does anyone know where I could
find any additional information on the dynamic update ability?

Be slow to attribute to malice what can be simply explained by ignorance or
stupidity.

They don't update your HD player, they update a list of HD players serial
numbers on each pressed disc. So your player will eventually not be able
to play anything new.
