Ironically, perhaps, this is the same quandary the networks find themselves in,
concerning multicasts. If they have no guarantee that the affiliates will
transmit the same multicasts, the networks don't have a lot of incentive to
create good ones. Or so I have read.

Bah. It would be so simple if each broadcaster just got his 19.39 Mb/s on the
MVPD, which after analog shutoff could amount to no more than 3 MHz of spectrum
on cable systems. Then no one would have to fret about what to strip off or not.
I can't get all worked up about this.
