Sky TV Problem

[Zen]

BBC 1 (Yorks) is all pixellated.
Men and Motors no picture says there is a technical fault with this channel.
ITV 2 is the same.yet ITV 3 is perfect. as are all the other channels
Been through the unplug system for a while perfomance to no avail.
Anyone got any ideas as to what is wrong ?

This happens to us when our climbing plants grow in front of the dish. Is there any obstruction, or maybe the dish has moved?

We had this and Sky would have charged us �75 to send someone out to re-align the dish. I found prodding it with a broom seemed to work quite well. Don't batter it too hard otherwise you'll need to get the Sky bloke out. Just a gentle nudge.
