Feature Request: playback speed

Sorry to beat a dead horse, but I wanted to watch tonight's game in 1.5x speed but the game is still recording because I extend it by 3 hours. Is there a way to manually end a recording without deleting it? Is there a "Stop" button somewhere that I can't find?
Thanks!

In the DVR web UI you can

Not sure how to do that from a client

In the client, tune in live and use the record button in the info bar. Or go to your schedule, find it, and cancel the recording.

@maddox I'm trying to watch today's game. The recording ended hours ago. But when I watch the game, the Playback Speed option is missing. This is happening on both my iPad and my Appletv 4K. I just installed the latest version of the beta as well.
