I will say that there have been some hiccups with the NBC Live App - I have lost my streaming several times, but was able to get it on the computer at NBColympics.com
And as for the network coverage I watched over 2 hours of cross country that I had taped ( I actually ended up deleting a lot of it bc I had seen it live) but it’s not on the regular NBC channel - it’s on one of the obscure stations. My Direct TV allows me to press the red button while the Olympics are on and I can search by sport then record that way. It’s really a neat feature and I can’t complain about any of the coverage. I think this is the most I have seen since I worked the Olympics in '96.
