Have you tried disabling Surround Sound?
Pretty sure that was mentioned previously in this thread I've never had surround sound enabled.
We are monitoring the HDHR stats for counters for if there were any MPEG-TS packets that did not decode properly. We had expected that it would detect all tuning issues, but it appears there's something special about the issues you're having that is corrupting the feed without causing the standard detection mechanisms to trip.
The reason why we asked for you to be on the latest build and for the [SNR] stats instead of just the signal stats you posted from the HDHR is that they can vary from moment to moment and our system is checking with the HDHR every 2 seconds and can detect momentary drops that would cause issues that otherwise would look fine. It also looks at some debug statistics that aren't presented in the HDHR UI.
All this to say: it's very odd that we aren't detecting this kind of error. Would you be willing to upload the file somewhere that we can download it to see if there are other artifacts in the file that we could use to identify corruption to present better errors in the UI? You can email [email protected] with the link.

You could check over at the AVS Forum in the section for your local TV reception https://www.avsforum.com/forum/45-local-hdtv-info-reception/446660-minneapolis-mn-ota.html and see if anyone else is seeing the same thing with K33LN-D. Maybe it's being transmitted that way.
I did delete the recording from the dvr, but did save a copy of the file elsewhere.
I put it on MEGA so u can download the raw file

Just an FYI on parts of posts I saved from Siliconduct support forum, since they fall off the edge of the earth after 3 months.
Your 87% Signal Strength is equvilent to -7.8dBmV
Signal Strength
100% = 0dBmV and a change of 5% is a 3dBmV difference, so every 1% change is equivilent to 0.6dBmV
A signal strength of 90% or higher is recommended for QAM operation, 80% minimum.
US Cable specs are 0dBmV +/- 12dBmV
A signal strength of 80% or higher is recommended for OTA operation, 60% minimum.
OTA ATSC minimun -30dBmV
OTA ATSC maximum isn't something that can easily be expressed, because overload is a cumulative result of everything going in, including non-TV signals like FM radio and LTE.
Non-TV signals often end up being a bigger problem than TV,since most people live a lot closer to a cell phone tower than they do a broadcast station, and most antennas are still designed to have peak gain at the frequencies that are now used for LTE.
SNQ & SEQ
For ATSC, 100% SNQ is 30dB+ SNR, 50% is 16dB SNR.
SEQ is a logarithmic scale of packets with errors in the last second, 50%=9, 0%=99+
Aiming an OTA antenna using the numbers
Use the Signal Strength for a rough idea of direction, but align the antenna for the highest Signal Quality, ignoring Signal Strength. When aimed correctly, Symbol Quality will show 100%, indicating no errors in the output. Splitters and amplifiers can introduce noise which will lower the Signal Quality, even if the Signal Strength increases.
