[vdr] Shutdown after recording

[Gerald Stieglbauer <gstiegl@cosy.sbg.ac.at>]

Hi there!

The normal use of a videorecorder is for recording and replaying. If the 
videorecoder is in the recording mode, which is initiated through a timer 
event, the recorder is woken up from a standby-mode. Then it records the 
broadcast and then it goes back into the standby-mode.

If using a computer with vdr, wake-up from the standby-mode is possible 
through writing into the RTC. The information when the computer has to boot 
is usually written when the vdr calls the shutdown script.

My question is now, which is the best way to put the vdr-computer to sleep 
again after a recording session, which is started after a RTC wake-up event?

For now I have only found two methods, which are unsatisfying for me:
1) Vdr shutdown the computer after the user-inactivity-time.
   a) is this time very long, the computer runs the whole night, which robs 
my sleep and waste power.
   b) is this time very short, the computer shuts down while cooking a coffee.
2) Using the "after recording script" to shutdown the computer. But how can I 
get the information for programming the new RTC-timer event, if there are 
further timers set?

One suggested solution would be: The recording script must return a value on 
which vdr decides to start the usual shutdown procedure.

Maybe there a some other ways, which I cannot see through my blindness. 
Please report them to me...

Thx,
Gerald.
