UPDATE: Sports4u has finished - 3rd September 2013
Yesterday (Thursday) BT Sports broadcast their new channels for the first time. Sports4U added the BT Sports 1 channel to Mash Up! It is claimed that the easiest and cheapest way to view is on an iPad or other tablet or PC via the BT Sport app, although most will want to be able to watch on an actual TV set. For reasons unexplained the app service is not available to internet-connected smart TVs - BUT you can watch on OpenView powered TVs - POW!
