Pixelation and skipping

So I’m recording the Oscars through my Roku 3. I have about an hour or so recorded and it’s still on air. I started watching the recording but it’s unwatchable due to choppy pixelation, video and audio skipping. Live TV has the same issue. Are there issues watching a show while it’s being recorded? All my other recordings and live TV are fine.

Pixelation usually points to weak signal. Could be an intermittent thing if signal is marginal.
