Uncle Google isn't helping here, but there must be a way to do this. Anyone know?

Let's say my friends and I are done watching a recording of a show, and then the Tivo sits there on the Now Playing screen after it is done. It's sitting there nice and quiet, and my friends and I are now having a nice conversation.

A few minutes later suddenly the Tivo flips over to Live TV all by itself and it's THIS FUCKING LOUD and it gives us a heart attack.

Surely there's a way to turn that off so that it just stays on the Now Playing screen and doesn't time out? Note: My TV is LCD so it is not affected by burn-in, so this isn't an issue.
