Heads UP regarding today and this week's US broadcast.
NBCSN will be broadcasting to the "NBC Sports App" today, Wednesday, and Thurday. I interpret this to mean that there will be no broadcast through your cable, Uverse, dish, etc. provider. You will need to use a streaming app (Roku, FireTV, Nexus Player, web player, Playstation Vue, NBCSN app, etc.). You should also be able to open a browser and go to http://www.nbcsports.com/
and login with your provider username and password. Then you will get exactly the same feed as the broadcast. I've been using this also and it works fine. Again, I believe this to be accurate but you're on your own so be prepared.
Also, America's Cup app for Android and Iphone.
and BT Sports live feed
