We must be talking about different things. The --host argument
is used to form the URL and should be the name of the host, as
in, the name in /etc/hosts. Which *may* be the same as the MythTV
hostname in its DB (used as a profile name.)

Could be that it changed in 0.28-pre then. Note that the key is not
Inputs/Input, rather Input is contained in Inputs. pastebin your
entire output if you like. I'll be a single line when you paste it
but don't worry.

You asked, I was hoping you'd know ;). But $? is the
return code from the last command executed. Perhaps:


yourScriptName ...............

RC=$?

if [ $RC -eq 0 ]; then
     echo "Tuner is idle....."
     ...
else

I never tried returning a string. I thought it was always a
number 0-255.  Where 0 = true and non 0 = false.

As to you other question, more *endpoints* are documented here,
although a bit out of data: http://www.mythtv.org/wiki/Services_API
