· wait.. I did what?
For the majority of the time there's nothing on any of the current 4K verizon channels, and the NBC content that's in the guide for the one channel isn't any good since nothing ever broadcasts there.1498 and1499 have guide data. Have you tried using a Wish List? You can set up key words and have them auto-record your shows. (Or will it not pickup the 4K channels at all?) 1494 and 1496 just say "to be announced" so manual recording is the only option.
Not saying I miss it, or would give up a Roamio if I could get it, just a data point, my Apple TV does a fine job with 4K streaming.
