Layered recording. How does it work? What is Layered Recording and how does it work? I didn't notice any changes between the checkbox turned on and off.
From the manual:

Layered recording
Adds a new NLA Track and strip for every loop / pass made over the animation to allow non-destructive tweaking.

I got it to work for producing new NLA track/strip by playing through the animation, setting the auto keying, and then moving the cube. It tends to create them when keyframing around the end and start frame.
