LiveTV ugggghhh....

I'm not sure how/why this is happening.  When a slave connects, the master
will set it's "sleep status" to either 'undefined' or 'awake'.  Undefined
is used if the slave does not have a SleepCommand configured, Awake is
used if the slave does have a SleepCommand.

So, your slave backend's sleep status should be changed to either Awake or
Undefined when it connects to the master whether it is started manually or
automatically by the master.

Are you assuming that the slave is still asleep because you can't use
it's tuner for LiveTV or are you looking at the master backend's status
webpage or the frontend's status screen?

If you are tracking trunk, I did fix one bug I noticed when looking into
this, but don't think it was related, but if you want to svn update and give
the current version a try, you can.  If you're on 0.22 and compile yourself,
you can try a 1-line change to programs/mythbackend/mainserver.cpp if you want.

If you're on 0.22-fixes, in mainserver.cpp, look for a line like this:

    if (!elink->IsWaking())

Change that to look like this:

    if (! (elink->IsWaking() || elink->IsAsleep()))

That will make it match trunk.  I don't think that will have much to do with
what you're reporting, but it's worth testing.
