Thanks, Flying Pram (That conjures up a wonderful picture!).
I don't watch a great deal of TV at the moment but recently my principal viewing has been the BBC News Channel.
I'll try to do some viewing on other channels over the weekend and I hope to be able to give you some more information in two or three days.
I know little of transponder allocations or polarisations, but is there a hard and fast rule, eg: are all BBC transmissions on the same transponder with the same polarisation?
Thanks again,
