Thanks for the prompt replies..
No recordings set for overnight..
I did not really think that the housekeeping had a human input..

but overnight U/Ds with the Tesco Freeview sprang to mind.. hence though that a remedial U/D had taken place..
Puzzled as to why it happens ...and indeed why i seem almost alone in reporting the failures..although I am aware that not everyones wife prefers watching on Sky and hence the recordings are dominantly unwatched.
Are you both saying it did not happen to you or are you both not in a position to comment for yesterdays recordings perhaps?
I will leave them.. ALL Seven.. blank to see if they update overnight tonight.. Quite coincidentally..
The lack of Thumbs when one copies to USB are most irritating to me.. as they are the recordings that I.. me.. actually want to keep

It seems so incompatible with a HI-tech device particularly as my very old Panny Hard drive copies the Freeview Thumbs to the DVDs ..Most people would construe that it's not Rocket Science but seemingly it is on FreeSat..is the technical background to that obstacle related to the overnight mechanism updates in any way?
To rub salt in the wound and more puzzlement.. the new Panny TV sets up the Thumbs immediately on the USB attached Hard drives on Freeview..Oh dear..
I feel a Rex Harrison song "Why can't.. " coming on.
