That's interesting. I just turned my box on manually to test this and,
like I mentioned in my earlier post, I looked at the value of $status (I
dump this to a file on start up as you can see from my settings below).
It says 'user' so the backend clearly knows it was started by me rather
than due to an automatic wakeup. I also just ran "mythshutdown -p -v
all" and it says "looks like we were started manually1" amongst other
However, I'm fairly sure I've seen these give contradictory answers on
an auto start but maybe I'm imagining it? I'll have to check it after
an auto start again to check this (when the wife isn't watching tv that
is :). I've checked the value the backend writes out several times and
that is always correct, I didn't know about mythshutdown -p til
recently, I assumed it would be using the same setting everywhere but

I think it wakes up 2 minutes before plus there's 2 minutes before the
show starts. My other settings are below, maybe you can compare them
with yours to figure out the key difference?
mythtv-setup (Shutdown/Wakeup Options):-
Startup command: echo $status > /home/myth/restartStatus
Block shutdown before client connected: unchecked
Idle shutdown timeout (sec): 120
Mx. wait for recording (min): 10
Wakeup time format: time_t
Command to set Wakeup Time: /usr/bin/mythSetWakeupTime $time
Server halt command: /usr/bin/mythshutdown --shutdown
Pre Shutdown check-command: /usr/bin/mythshutdown --check
mythSetWakeupTime is just a simple script to put 0 in rtc then $1 and it
works fine, no problems there...
Command to set wakeup time: <blank>
Wakeup time format: yyyy-MM-dd hh:mm:ss
nvram-wakeup Restart Command: <blank>
Command to reboot: /sbin/reboot
Command to shutdown: /sbin/poweroff
Command to run Xterm: xterm
Command to run to start the Frontend: /usr/bin/mythfrontend
My theory is that you have to call mythshutdown --setwakeup for all this
to work properly. Note from above that I directly set the wakeup time
without going via mythshutdown. This is because its a pain in the ass
if you're trying to use RTC because it seems mythshutdown --setwakeup
wants date-time style input.
If that's the case then I'd guess this might work but I've already tried
lots of different guesses without luck. :(
Wakeup time format: yyyy-mm or whatever it is.
Command to set Wakeup Time: /usr/bin/mythshutdown --setwakeup $time
Command to set wakeup time: /usr/bin/someScript
...where someScript will have to take a date-time and convert it into
seconds since epoch.
