So the whole mechanism is dependent on using mythshutdown to tell the database when it needs to wake up, but there's also a configuration setting in the backend config for how long prior to a recording to autmoatically wake up... then when it actually wakes up mythwelcome ignores both of these and just uses an arbitrary "are we within 15 minutes of a recording" test to guess if it got started in order to do a recording? 
So I also don't get a frontend if I happen to manually power up the mythbox within 15 minutes of the next recording?
Is it just me or does anyone else also think the whole existing mechanism is seriously overcomplicated, especially for something that doesn't work right anyway?
 
Could I suggest we do away with mythshutdown entirely and when mythwelcome starts up just have it directly read the time last stored in the RTC flash and compare it to (system time - uptime). That would seem to be a much simpler, cleaner and more accurate way to figure out if the box was started by automatic wakeup or by the user.
