Yeah, I saw the 'alternate broadcasts' with the Next Gen stats. It's not my bag, but it is an option that some people might like. I did like the way they had a ghosted 10 second fast forward, rewind, and stop/play in the center of the screen. I was watching it on my tablet and found it a lot more convenient using a click of the mouse to rewind something that I had missed while I had it minimized to my task bar. It was a lot easier than using the slider at the bottom of the frame.
One thing that I did notice that was odd was the time delay between different methods of streaming. I have two TV's fed from the same router that I was running Prime Video on. One was a smart TV, the other is an older model that runs off a Roku stick. The smart TV was WAY ahead of the older set with the Roku. Two different processors? I'm not much of a tech guy.
