I've noticed for a few months now that some recordings seem to disappear as though they have been deleted. I was about to watch something I recorded a few weeks ago and that wasn't on the list anymore. I have at least 50% HDD space left and I do not have any auto delete oldest recording setting enabled. I don't understand why random recordings just go. It's not even the oldest ones on the list (I have some stored from last Christmas).
Does the Humax do some kind of purge based on broadcast settings? What I mean is that for example if you look at BBC iPlayer, it shows content and says an episode expires in X amount of days. Does Freeview recordings have such a feature that forces a delete based on an expiry date?
