One of the biggest problems that is that the current DTV TRANSITION channelization can easily have a VHF analog broadcasting the DTV digital on a UHF channel. POST-TRANSITION the DTV digital could either end up back on the existing VHF channel or on the current UHF transition channel or a new VHF orUHF channel...BUT from the USER point of view the channel number will not change! Thus a channel 4 analog might be broadcasting digital on channel 45 pre-transition and end up on channel 20 post transition; but the channel you would enter on the TV will still be channel 4-1, 4-2, etc. Talk about confusion! It will take at least a generation to straighten this mess out IF over the air television survives.
