Yes, and note that this is TRAMNSMISSION-defined; 100% BARS is a totally
legal NTSC signal, this is why we keep fussing about transmitter legal as
opposed to gamut legal (for this discussion, anyway).

Another good point, Chris.  You really need to get (in writing) the delivery
specs for the final product.  Don't depend on a middleman; if the show is for
PBS, get the PBS specs, don't go by what any interim production company says,
because when the feces strikes the airscrew, you'll still be held accountable
since you were the last one with your hands on the buttons.
