*IMPORTANT* - the slave backend (SBE) needs to be configured so that
it can connect to the master backend (MBE) and database.

You may need to give access to the SBE machine in MySQL (covered in
the official mythtv docs) if you haven't already, and possibly enable
networking in /etc/my.cnf (the MySQL config file). On the SBE, the
~/.mythtv/mysql.txt file will contain the settings for connecting to
the database.

Getting networking sorted is probably the biggest hurdle. Adding the
extra capture cards on the SBE is pretty easy.


1) Configure the new capture cards on the SBE using mythtvsetup on SBE

2) You do not create/configure new video sources on the SBE, these are
only ever configured/created on the MBE. Once you can connect to the
MBE/DB MythtV will have access to the video sources available on the
MBE machine.

3) Enter Input Connections in mythtvsetup on the SBE machine and
connect the correct video sources to the inputs on the new capture
cards you have just configured.

4) Once this is done (and you've made sure the capture cards are
working normally on the SBE), the newly added SBE capture cards should
be available (whilst the SBE is connected to the MBE) and you should
also be able to view program listings on the SBE.

5 You can check the system status in MythTV and using mythweb, and
should report the extra capture cards as available, and the machine
they are on.

HTH,
