 From the MANUAL:

   Min. event timeout = 30
   Min. user inactivity = 300
                          If the command line option '-s' has been  
set, VDR will
                          automatically shutdown the computer if the  
next timer
                          event is at least MinEventTimeout minutes in  
the future,
                          and the user has been inactive for at least
                          MinUserInactivity minutes. Setting  
MinUserInactivity
                          to 0 disables the automatic shutdown, while  
still
                          retaining the possibility to manually  
shutdown the
                          computer.

There is your 30 mins.  No bug, a 'feature'.

My VDR is set to these defaults.  If I try to shutdown before 30 mins,  
I am prompted by VDR to press Power again to FORCE shutdown.  If this  
is the case I cannot recall exactly but I think the wakeup is set to  
30 mins from the forced shutdown, rather than the next timer.

If I recall a mailing list discussion there was an argument along the  
lines that if a timer was set to record in less than a certain value,  
30 mins by default, it is 'cheaper' in terms of power and hardware  
shutdown/restart cycle degradation to keep the computer running.

I have not played with this setting so I cannot comment on VDR  
behaviour with a lower setting for this value.  Please report back if  
you experiment.

Seasons Greetings,

Ian.
