As long as they have IPV4 addresses, it will use those. If they have 
only link-local addresses and no other IPV4 or IPV6 addresses, I think 
that nothing will work. would that be a valid configuration? Internet 
searches indicate to me that link-local addresses are of limited use and 
many applications do not support them.

I think you are correct, that the issue would have gone away if the 
"Listen on Link-Local addresses" checkbox was unchecked.

But, unless the client was changed in some way it would fail unless you 
uncheck "Listen on Link-Local addresses". The client does not know to 
use a specific interface to talk to the backend with a link-local address.

I am trying to help the new user who just installed MythTV and does not 
want to get hit with "Unknown error" the first time they attempt to run 
the front end.
