 From the master backend host, run mythtv-setup and select the "Live TV" 
Storage Group entry and hit DELETE (D).  That will delete the Storage 
Group definition completely (including all overrides on other hosts).  
You could, then, re-create the "Live TV" Storage Group, but you probably 
are better off without it (99.99999% of users shouldn't define a Live TV 
Storage Group, even if they use Live TV).

We don't really have a good way of clearing out old, non-existent videos 
from old, non-existent hosts in Video Library at this point.  I don't 
know what all needs updated, so I'd recommend you let Video Library do 
the right thing.  To do so, temporarily start up mythfrontend on any 
host using the <LocalHostName> override with the old 
"local-localhostname" and--with your Videos Storage Group directories 
temporarily empty or non-existent (just rename the directory(ies) for a 
moment)--go into Video Library and scan for changes.  That should remove 
all videos from the old host.  Then, exit mythfrontend, rename your 
Videos directories, and go back to your original config.xml (with the 
appropriate LocalHostName).
