off topic ish) i know but as this is about auto shutdown etc i thought i'd chip in. In ViX ( yes i know here he goes again about that flaming ViX image when the thread is about BH, but bear with me ).
In ViX you have a feature called power timers, this plugin was specifically rewritten by andy to provide such a function and much much more, you can set timers from here for auto shutdown, reboot, power up at any time.
For example you want the receiver to go into deepstandby but want it to wake again for the EPG ang again go back into deepstandyby afterwards then awake for breakfast every day,
you set the power timers to go into deepstandby at say 01:11, then wake at 04:00 for the EPG to download at 04:15 then again go back into deepstandby at 04:25 and once again wake at say 07:00 in time for the kids to get up and get ready for school. Now i'm vastly simplifying things here but i hope to be ale to show just a little of what is possible with dedicated embedded features rather than tacked on plugins in a image.
