Well, I guess I'm one of the lucky ones. I tried out all five of my Harry Potter BDs this morning. All five of them load quickly and seem to play flawlessly. Now, I only watched a few minutes of the earlier ones (1-4) and tried some chapter skips and special features, but didn't run into any problems, including the ballroom scene from Goblet of Fire. They're all singles, most of them bought from the big Amazon BOGO before Christmas. I was disapointed that Goblet of Fire had the beige artwork as opposed to the photo art on the disc, but as it plays correctly, I think I can live with that.
