I don’t see a call button on the IFE, so maybe A300 or 757. The low placement of the IFE control might give it away (outboard seat).

The chime is at 1:46, but is ruined by the music and the fact that the pilots cycled the fasten seat belt switch twice to signal the attendants for landing (4 chimes instead of 1).

That is a much higher neutral point than the L-1011. I’m glad that the system was finally used on another airplane.

Is there a steep approach switch in the cockpit? The L-1011 used a 30 degree flap switch to activate DLC.

You can see DLC in action in this video. When the flaps are deployed from 22 to 33, the spoilers assume their new neutral at 3:53. After that point, when the pilot pushes forward on the yoke the spoilers retract. When he pulls back, they deploy further. http://www.youtube.com/watch?v=Vf2nFYHKGuU So...
