Are we really using channel number for the HDHR Prime?  We shouldn't 
be.  We should be using frequency ID, as we do for every single analog 
tuner in existence.  That allows users to specify the virtual channel 
number for the frequency ID and use whatever they want for their 
(display-only) channel number.  By default, the frequency ID for a 
"tuned by channel identifier" card/input will start out the same as the 
channel number.

Definitely true!  You should use one of the 3+ channel editors we have 
provided--the mythtv-setup channel editor, the MythWeb channel editor 
(which is great for "batch" changes), or the mythfrontend channel 
editor--to change any channel-related data.
