I have a Pioneer DVD/LD unit as my main player, and at exactly 84:01 into the movie, where the layer change is, it locks up and won't keep playing. I've read that this turned out to affect most Pioneer players out there. I called the 800 number and talked to a technical person, but he didn't seem to think this was too big a problem because it was at the layer change and my player was an 'older' model, even though it's never had a problem this big with a disc before! Yes, you can hit Chapter Skip forward to play the rest of the movie, but I don't want to have to do that. I won't buy any more DVDs from Buena Vista until this problem is fixed!
