I am using Channels DVR on a Toshiba Laptop, and have been using this configuration for several years. Lately we've been getting a lot of pixelation. I've checked the antenna signal using HDHomeRun Config GUI and it is good... 83% signal strength, 100% for both signal quality and symbol quality.
Channels DVR is version 2022.03.23.0209.
How can I troubleshoot this further?
