The new Windows 8 apps are good to have a look at. One of the newest apps is FilmOnTV. The Windows App streams lots of British tv channels in SD quality for free. But they offer much more! Even for you without PC or Windows!
If you visit you will find lots of free channels to choose from. Here you find not only British, but also French, Spanish, Italian and German channels that you can stream for free. We have streamed TVE (the Spanish national channel) some few hours and can report that the streaming starts immediately. There is no buffering time at all. It is also very stable, no hanging or delayed signals. The SD quality is of course not stunning, but acceptable.
In Norway the TV channel providers use to charge a lot for this channel, so FilmOnTV’s service is good value.
