I think part of the confusion is that historically with analogue 
we've had one radio channel == one (analogue) stream == one program, 
but now under digital we now have one radio channel == one (digital) 
multiplex == multiple programs combined (multiplexed) into one 
digital multiplex.
IE, the thing that people need to learn is that now Radio channel != 
Program channel any longer, but of course we still use "channel 
numbers" to identify programs AND to indicate a frequency to tune :-/
