Query: Great film, defective DVD

I have to agree with earlier posters that this is indeed one of the scariest films ever made. I can't praise it enough. However, I had a real problem with the DVD hanging up and dropping back to the menu about 1/3 of the way into the film. I tried 2 different DVDs (both purchased at amazon) on 3 different players, and not once was I able to get through the entire film. Obviously, this is a manufacturing defect. What I don't know is if it is just a bad lot (both DVDs were acquired in Dec. 2005), or if every copy has this problem.
