Requires activation by providing a valid NBC channel provider — which in my case was DISH. Easy enough PROVIDED you do have a provider. Worked quite well though it takes a few minutes for the activation to kick-in and it is BEST to RESTART the channel. You should then see the name of your provider (e.g., DISH) appearing next to the NBC logo at the top of the screen.
A good way to watch the Olympics on NBC. Maybe the ONLY WAY. Yes, there are commercial.
But most of the Olympic events are separately catalogued and there are separate highlights, features and replays. Better than DVRing all of the NBC coverage and trying to find what you want to watch.
