Something wonky. 2.35:1 widescreen should show up as you are accustomed, with small black bars at the top and bottom of the screen.
It may be as simple as a one-time synch error between the TV and player. Are you playing the disc on a DVD or Blu-Ray player? What model and I'll look up the settings.
First, though, check that your player output is set specifcally to 16:9 and not "auto" or some other variable. The player defaulting to a 4:3 aspect ratio output could result in a 16:9 TV displaying the image as shown in your pic.
