Are there limitations on how big the video can be? I experimented by recording from 8:30 PM Eastern to about 6:30 PM Eastern, and got an 8 KB file with no video. If it helps, I was recording to a 256 GB Micro SD card on a Surface. I had no issues when I recorded Match Game 75, Sale of the Century, and The All New LMaD. (FWIW, one contestant on Sale last night was Kyle Gass. He went on to become the half of Tenacious D not named Jack Black.)
