The PlusNet TV service seems to be live. Lots of extra channels available to PlusNet customers on 15Mb+ fibre. We have a Humax Freeview box and the chanels all just appeared. Very interesting selection, depends on costs. More info here (though still not mention of costs, you have to phone!)...

Is anyone using this yet? Unfortunately our new build house only has a 1.5Mb line...
