With the Olympics here I was expecting lots of 4K content. But all I am getting is problems. Last week I tried to record an ondemand 4K show. I got a message that I had insufficient bandwidth, despite having a 60Mbps hradwired feed. A technician visit resulted in my hopper-3 being replaced. So that one solved. Last winter, I recorded a few 4K football games. But had trouble watching them because of a Copy Protection error blaming an insufficient cable. But the cable is not the problem (and I have tried many). Now with the Olympics, that messages seems to pop up occasionally on 4K stuff, but then after a few seconds goes away. It seems the Hooper is oversensitive about having an adequate cable. There are TWO 4K olympic channels but hardly any content. Nothing on one (the Golf one) and on the other just wee hours in the morning tennis. Mostly those channels show just a graphic saying "Stay Tuned". Nothing in primetime. My broadcast area is Charlotte NC. NBC's schecule shows lots more being broadcast in 4K. Things like fast forward work real poorly on the recorded 4K stuff. It seems like the Hopper has insufficient horsepower to keep up with the content when doing a 60X or 300X fast forward. Are others finding the same limitations on Dish 4K or is it just me?
