Hmm, step 9, the cards .. are configured on the machine where they
physically reside. If a SBE goes down, on the status page, you'll see:

"Encoder 3 is remote on SLAVE_HOSTNAME (currently not connected)"
.. the MBE continues on it's way, rescheduling where appropriate.

BTW, can you define "see the capture cards", how? If configured,
http://MBE_hostname_goes_here:6544/ would show Tuner stats. [Likewise
:6544 on SBE shows Tuner* stats, but only for that SBE's card(s)]

mythtv-setup on SBE: you should see the videosource from the MBE (menu
option 3), just don't configure a new one. Then, under input
connections (menu option 4) this source should be available to your
SBE card.

If not, then it sounds like a MySQL issue of some kind. 

I'm not sure what the docs recommend, but I'd move your step #6 to #1.
The mythtv-setup program needs the MBE IP/port configured in order to
retrieve available videosources, etc.

If you're unsure, a quick way to verify mythtv-setup on SBE is
connected, would be to run 'mysqladmin processlist' on the MBE. There
should be 3 threads (I think), with the user at SBE_host you're
expecting.

I mean no disrespect, but it should be a straightforward setup -
therefore, instinct tells me it's something simple being overlooked.
Then again, I don't surprise easily .. unless something works on the
first try without reading the docs - then I worry.

FYI: I just setup my (1st) SBE in the last 48 hours, but it worked out
of the box, first attempt, recordings and scheduling all in order,
playback = good, "failover" to MBE-only = good.  Ultimately, this
slave will probably take over BE duties, but I can't miss recordings
in the meantime. ;)
