You told mythfilldatabase to change tons of stuff about /all/ of your 
channels, regardless of whether that data was ever modified by you or by 
the channel itself since you first created channels.

Data now may or may not be the same as data the first time you ran it 
(channels change things, and SD/TMS update that info).

Basically, you shouldn't ever do a --do-channel-updates.  Really, if 
you're at the point where you want that (change all channels to whatever 
my listings show), you're better off doing a "Delete all video sources" 
and then "Fetch channels from listings provider" because 
mythfilldatabase may or may not be able to properly link old and new 
data to the proper channels.

Again, likely the "can take a long time for changes to propagate."
