I've had 4 timers set on one of my 622's for at least 2 years and they are all set to record new episodes only. They've been doing just that until this past week when they are all recording old episodes that have old original air dates in the guide info. I've seen it happen when the guide info has no original air date but these all do. I've checked the timers and they all say "New episodes only" so I don't know what's going on. The other 622 is fine.
