It's funny, there were times while watching the DVD I wouldn't hear applause but could have sworn it was there before, and other times I could hear applause but could have sworn it wasn't there before. I just thought it was from me not paying enough attention.
But now that you brought it up, Craig, I decided to check it out.
I first set the audio to the way I usually listen to it, in surround sound, and I could hear the applause. Then I switched it to stereo and did not hear applause. I compared it to the PBS version, which was only in stereo (even though it was in HD), and I not only heard applause, but it was louder and lasted longer than it did on the DVD.
I don't know how it happened, or if it was intentional or not. But at least now I know why I would hear it sometimes and other times not.
