I'm trying to burn a video to DVD using DVDSP. When I simulate it everything's fine, all my chapter markers work, my menus work, etc. But when I click burn I get the following message: "Final Sequence-Product Runway-MPEG-2 6.2Mbps 2-pass, Chapter 2: Marker position in movie not at GOP boundary" "Build Cancelled" I've never run across this error before. I've edited the movie in FCP 6, and placed all my chapter markers there, then used Compressor with "DVD: Best Quality 90 minutes" as my output settings. Shouldn't either FCP or Compressor automatically place a GOP boundary at my chapter marker? Is there a way to manually force this if it isn't doing so?
