[Satellite and digibox setting up advice]

I own a house in dept 64 . The house has an existing satellite dish approx 30cm diam which points south eastwards.

At present i use a normal aerial to get French terestial channels 1 -4 .

I would like to receive main UK terestial channels possibly with CNN or Sky News also.

Can i buy any digibox in the uk that willconnect into my modern tv and French satellite to give me these channels .

Will i have to move the direction of the satellite dish to receive these channels ?

Many thanks for any advice by 6 Feb .
