Query: Cannot access special features with my Sony BDP-S570 player

I just got this Blu-Ray disc yesterday, and it has been a major disappointment. "Good Night, and Good Luck" is a great movie, but the Blu-Ray edition has problems with my player. When I go to the Menu and select "Chapter Selections," I cannot move forward or backward on the chapter selection bar. Also, when I try to access the "Special Features," it takes me to that menu, but it doesn't let me select any of the bonus features. I can't even click on the "Return to Movie" button. When I hit the Stop button on my remote and then his Play, the disc goes back to the very beginning of the disc (the piracy warning, etc., before the film starts.Is this a disc-authoring problem, or a problem with my Blu-Ray player (which wasn't cheap, by the way)? I have already added the most recent firmware update, but that hasn't solved anything.Glad I still have my regular DVD of the film. I may have to return the Blu-ray disc to Amazon.
