Hi,
Cheapest option for france is to use a digital TV, if you have one. It is easy to set up using the TV set up menu, and you will be able to view the various French Channels, as these modern TV's are set up for varies countries.
WiFi is not an option on the BBC, as reported, the channels are blocked, and you can only get newscasts.
satellite is the other option, but it is expensive, and you have to 'lug' the equipment around.
Last time the football was on we were in France, we used the camp site TV room and joined in the atmosphere with the rest of the campers. France playing Holland, great game and it's what being 'european and camping' is all about.
