Additional information.

Selecting the CableCARD tab from the hdhomerun setup program in the 
hdhomerun_config_gui Windows package, shows a full and complete list 
of virtual Comcast channels with their corresponding names. Clicking 
on the virtual channel number launches VLC and streams the correct 
channel in all cases.

Assuming I have screwed up the virtual channel map to myth, how do 
reset it to be correct?
