I was watching TV last night and finished watching a film I had recorded on the BT TV box, so tried to delete it. It seemed to taker a long time to achieve the deletion and I noticed three small dots appeared next to the recording "picture". I got bored and started watching something else. When I switched the BT box on this moring all my Xmas recordings had vanished! The TV box was about 30% full. Help!
It sounds like you deleted a whole group of recordings, and not just that single on. I do not have the new BT YouView interface, so I cannot comment on the three dots, but I expect it means multiple recordings.
