If you override the definition of the ChannelIcons SG (on the master 
backend***), the directory/directories you specify are the only ones 
used--by the code that actually uses the ChannelIcons SG.  I don't know 
the current status, but a while ago, only parts of the code actually 
used the ChannelIcons SG and the rest of the code /required/ channel 
icons to exist at ~/.mythtv/channels .

if you're willing to fix code that doesn't use the SG to convert it to 
use the SG and you're willing to encounter breakage on your system 
(rather than just having it work properly and not worrying), your best 
bet is to put channel icons in ~/.mythtv/channels .  And, if you're 
worried about having multiple copies of your few megabytes of channel 
icons on your multiple hosts, you can still have a single copy on the 
network with symlinks and/or network file systems. (Meaning, IMHO, 
there's no reason to ever override the ChannelIcons SG definition).

*** If you override the definition of the ChannelIcons (or any other) SG 
on any non-master-backend host, the override applies only to that host 
and the master backend (and all other) host(s) will use the built-in 
(master-backend-defined) definition.
