I understand that, it would catch some but not all problems, the goal  
being to re-record something that was obviously missed. Nice feature,  
but not a too-high priority.

You might also integrate some way for Myth to know if the system was  
running on UPS battery power, the assumption being that recordings  
during that period might be suspect due to cable box/sat rcvr being  
down or having switched channels due to a power glitch etc.

Everyone *does* have a UPS on their Myth systems, right ?? :-))

I still remember the time we had a power failure at the transmitter  
and a manager in all seriousness instructed the Master Control  
operator to put up a graphic saying "We are Off The Air".

Last I heard that manager was a vice-president.
