I too have had this same problem - last week I encountered the same mess with Balls Of Fury. With that disc I returned it for a new one and had no problems. With The Kingdom I am now on my 4th disc and I still cannot get this to work. I have tried 3 different DVD drives on 2 different computers and nothing is working! If anyone has any help other than "it worked for me" it would be greatly appreciated by those of us who are stuck with this one! Thanks!
