My old Pace box once moved by itself! I came downstairs to find that it had moved forward and people were jokingly telling me the download that occurred that night had been sent too fast!
Another time, whilst watching a programme about ghosts, now/next erroneously changed to "Strange But True"!! I was told that this was from the ftn channel.
Joking apart, whilst I do believe in spirits (seen them) and I think that their presence can affect electrical equipment, these things are often caused by more down to earth things. eg people say that low energy light bulbs can cause problems for satellite viewers and for the old On/ITV Digital.
When I first moved into my house, ATT would often change channels by themselves. A neighbour said that the lady who I bought the house off didn't like long programmes like films and preferred shorter half hour things. We used to say that she was turning the TV over from the spirit world if she didn't like what was on
