BBC Prime, CNN, BBC Word News, Theres a couple of sports ones as I remember and a couple of french chanels that do fairly up to date movies (they have a dual soundtrack so you can opt for french or english. Apart from the already mentioned chanel 47[:0 that's all I remember anyone know any more?
You can also opt to purchase a smart card which gives you loads more films etc, but I han'nt bothered with this yet.
