Last night my Aura had a complete 'Failed Recording' fest. I had it programed to record successive programmes on BBC One HD ('When Paddington met the Queen' and the film 'Paddington'); Channel 4 HD ('Lost Treasures of Rome' and 'Hitler: The Lost Tapes'); and also BBC Three HD (the film 'Insurgent').
'When Paddington met the Queen' recorded 3 minutes and cut off before the end. The film 'Paddington' recorded 53 minutes and then stopped. 'Lost Treasures of Rome' recorded 50 minutes and then stopped, and the film 'Insurgent' had two failed recordings with zero minutes. All the recordings were marked with the 'Failed Recording' symbol with the reason given as a power failure. I was not aware of any power failure during the evening (not even a dip on the lights).
Possibilities to consider: earlier in the evening I had been watching Channel No. 601 and the Aura was left on this channel. At the time the recordings were supposed to happen I was watching a film through iPlayer but directly off the TV, not the Aura.
I've never had any difficulty recording 3 simultaneous programmes in the past, even when the channels were spread across a mix of multiplexes, both HD and SD. So I have no idea what happened. I'm just hoping that tonight's mix of BBC One, BBC Two and ITV all recording at the same time manages to work, or else I'll be hammering the Catchup apps. Fingers crossed!
