Reboot loop/MOCA causes TV connected Cable Box to Pixellate (long)?

I'm looking for some help with an explanation as to why a Roamio stuck in a reboot loop with a Mini 4K and cable box in a separate room both hooked to another tv would cause pixelization on the cable box output. When I turned off MoCA on the Mini, the pixelization on the cable box disappeared!! I'm dealing with TiVo support on the reboot loop issue on the Roamio, but curious how this is affecting the cable box output.

I thought it was coincidental, but a few nights after the reboot loop...
