Solved.... I pressed the red button on my remote to see what it was showing when I had the HD channel selected and just a black screen. (This is on one of my hoppers, not a joey). It showed Tuner 1 Available, Tuner 2 Available, and then Tuner 3 being used by the 4 local stations. The list of 4 channels showed 2 "Watching" 1 "Recording" and KARE11 showed something like "Watching in PIP". I was like, pip? I used the PIP stuff earlier this day but not recently. So I chose that show and selected it. It then prompted me to join 2 different streams of that show, both of them listed as the Living Room with the same times (which was where the hopper was that I was using. So I picked one and bang. I now have KARE11 in HD.
Apparently something glitched in the PIP stuff stranding that channel in a viewbox that wasn't on the screen. But selecting it from the app behind the red button the remote allowed the system to reset and get the data.
Very weird, and while I'm sure rebooting the receiver would have solved it as well, I'm glad I found a way to see it in HD and not reboot the receiver.
