Other than being a watermark and probably more crytographically 
secure.....is this really much the same security model they had with DVDs 
using CSS = Trusted hardware? Or am I missing something in the 
announcement?

The solution?  Watermarking (which as we know, can mess with the picture).

"Technical plans aren't final yet.  But essentially a watermark would 
insert
instructions directly into the movies that would tell DVD players and
recorders whether a movie could be copied. If it was copied illegally, the
movie could not be played on hardware that included the 
watermark-recognition
technology."
