Nonsense. Region coding, encryption (e.g. CSS), expiring content =
(e.g. DivX) are examples that existed without pre-existing support from =
software vendors. These and the other forms of restrictions all exist =
because the content providers require it. Microsoft, Apple, real as = well as
CE vendors (e.g. Pioneer, Creative, Apple) support it only = because it is

If the content protection in vista goes above and beyond that found =

Yes. However, the use of additional CPU cycles is inevitable, as =
