But if it did that, since channel numbers have to be unique for channels 
on different sources, how would you tell Myth that multiple channels on 
different sources broadcast the same content.

Channel numbers are used by the person to change channels in LiveTV and 
must be unique.

Channel ID's are used by Myth to identify/change channels and must be 

Callsigns are used by Myth to schedule recordings and /can be/ (but do 
not have to be) the same for channels broadcasting the same content.  If 
two channels broadcast the same content, the user may decide to specify 
different callsigns so that he/she can tell Myth which channel/source to 
use for recordings.  For example, I could specify a different callsign 
for WKMG (Channel 6) and WKMG-HD (Channel 6_1--the high-def version of 
channel 6) so I can tell Myth whether to record shows in SDTV or HDTV.  
Or, I could specify the same callsign for both the SDTV and HDTV 
versions so that Myth can choose which to use (and, when couple with 
appropriate preferences/priorities, Myth can be set up to choose the 
appropriate channel for recording).
