This problem has happened on a number of occasions and I'm wondering if this is a fault with my model or something that is affecting everyone.
All of my series record programmes for the 12th haven't recorded.
When I switched to the HDD recorder today using the sync menu on the TV remote it became apparent that the HDD has completely switched off at some point as the start splash screen came up before showing the channel and then immediately started recording one of the programmes I had set to record today (the F1 coverage, of which a good chunk had been missed)
Is there something going on with the over-air updates that cause the the unit to switch off or is this just some sort of random fault?
If I go on holiday and this happens I miss all my programmes as it doesn't start recording until you switch the machine back on again and so makes the unit totally useless to me 
thanks,
David
