5+1, that would explain it but I deliberately re entered 105 so I don't think so. If other people here did watch it on Virgin at 5.30 I think it's a Twilight Zone situation, but the first thing I did was press i to check and then enter the correct channel again, I would have been unlikely to have done that for 5+1 as I wouldn't have been sure what to enter without checking. Very odd (unless anyone else reports it, this was the London area in case they vary locally).
