@YouTubeTV when I’m recording something to my library, I want to watch from the beginning even, or especially, if it’s still recording. If I’m delaying a sports event, I DON’T want to click play then have it pick it up live.
If you add a program to your library while an episode is in progress, your recording will start from the time you added the program. If a rerun of the episode airs, your partial recording will be replaced by a full episode. More here: https://yt.be/help/vwjo . Hope this helps.
