I don't fully understand the nuances of video levels for Dual Link, HD 
and data, and what that means for workflows.  Can someone please 
describe the nuances here?  In particular, are there secret codes 
stored in the below-black and above-white regions?  In the pure 
digital realm, do these regions really need to be preserved for 
post-production?  Lastly should the united states department of 
homeland security be concerned about those secret codes?
