We are sorry to hear that you are annoyed by the edits to the programme. The programme was bought and is scheduled for a 6 o'clock slot. From time to time small edits have to be made in order for us to comply with the ITC code. It was bought for 6 o'clock because that is a part of the day where you get a broad family audience. The show appeals to both and younger and adult audience, however we have to ensure that it is suitable for a pre-watershed audience.
We hope that this explains the situation.
It still doesn't explain why they don't move it to a later slot though, sort out all the problems, but the ITC theories were right though.
