Losing program display during live TV

This just started happening. Watching a live TV channel that I’m also recording. Screen goes black and I get the spinning circle indicator. Lasts for 30 seconds or so. No error messages. How could the Quad be so busy that it can’t process a live TV feed?

I’m using the new Quad Tablo with 1080p streaming and recording. The Quad and the TVs are using the Tablo Roku app connected via 5G Wifi.

I also noticed that the recording of this program said it was still recording over an hour and 30 minutes past its scheduled run time. I had to manually tell it to stop. I haven’t changed any of the default start and stop times and the guide correctly showed the length of the program.

We’re you watching a sporting event? If you have “extend live recordings” checked in your settings, then special events like sports get an extra 50% recording time.
