I noticed something similar on some DVDs from Warner, which were split over two discs. If the entire movie has e.g. 50 chapters, and the first part on the first disc has 25 chapters, then the 2nd part on the 2nd disk still has 50 chapters, but the first 25 chapters are all on the first second or so. When playing the second disk directly from chapter 1, I have major a/v-sync issues, which resolve themselves within around 30 seconds or so, but playing the 2nd disk with -chapter 26 plays fine without any a/v-differences. -- cheers, Alex
