In the settings table:

i) The Master Backend should have value='MasterServerIP',
data=''your.ip.address' and hostname='NULL'.
ii) Each backend (the master backend and any slaves) should have
value='BackendServerIP', data='backend.ip.address' and

mysql> SELECT * FROM `settings` WHERE `value` LIKE '%ServerIP%';

You can also run:

mysql> SELECT DISTINCT `hostname` FROM `settings` ORDER BY `hostname`;

to see whether you have old/conflicting hostname entries in the settings table.

Your slave machine will have either a mysql.txt or config.xml
configuration file for MythTV in ~/.mythtv/ for the frontend and
backend users (and possibly elsewhere too). To be on the safe side,
check that these contain the correct settings for your current
database configuration.

I'd also recommend the full 'Delete All Capture Cards' on the master
backend machine, adding back your cards in order of preference,
highest first. This doesn't touch your channels configuration - you'd
just need to reconfigure the Input Connections on the master and slave
backends with the existing video sources.
