I have composed below a set of common questions regarding television and satellite options when in France:
Yes and No. British televisions use the PAL (Phase Alternation Line) system of receiving analog television but in France they use the SECAM (Sequential Couleur avec Memoire). Your British television would probably be able to pick up a picture but it would be in black and white and the sound would be distorted. However, if you take your satellite dish and box with you to France then you will be able to view British channels on your television as you would at home.
I am not even going to try and answer this question when there are many sites around which dedicate themselves to answering this question. Take a look at David Sullivan's satellite site for full instructions on how to manually set up your dish.
Yes, although as far as I am aware SKY do not officially allow it so you will have to find a friend who will allow you to use their address. Your monthly subscription will also need to come out of a UK bank account. If you use a FTV (Free to View) card then this won't trouble you.
A FTV (Free to View) card is a SKY viewing card that gives you access to ITV, Channel 4, Channel 5 etc for a one off payment of around £22. BBC should be available without any subscription card at all because the BBC have left the SKY.
The information I have provided here is at a very high level. If you need more then drop me a line or use one of the following resources:
