  I expect that most will get it right.

  When a local station (univision) stopped transmitting their PSIP
correctly,
their digital channel disappeared from 14.1 and appeared on 51.1.  A few
months later when they figured it out and reset it, the next time the set
saw
their signal, it moved them back to 14.1.  (The set was a Sharp.)
