This opens up the discussion about whether VDR should handle external 
tasks together with timers. I think that VDR should only handle its own 
tasks.

A timed start could trivially be done by setting a daily timer. More 
elegant, the shutdown script could check whether the wakeup time is past 
3:01 and simply set a different wakeup time. With some reminder it could 
also realize that the machine did wake up because of the 3:01 tweak, and 
give special instructions - like starting EPG scan and shutting down (or 
going inactive) after 10 minutes.

Cheers,

Udo
