It looks like chapter track detection may not work properly in some cases.

There are 4 titles on this disk. Titles 1 and 2 are the movie. Titles 3 and 4 are the movie with "video commentary" (images from production rendered on top of the movie, pretty silly). The length of the video is the same for all titles - after all, it's the same movie.

eac3to seems to detect the chapters list just fine for titles 3 and 4, but not for 1 and 2. I can't quite believe that there are no chapters for 1 and 2 since that is the actual movie that most people would watch.

Even if I run eac3to directly on the .m2ts files, it's the same - it can't find any chapters for 00008.m2ts but it does find them for 00011.m2ts

In this particular case, I can probably extract the chapters from title 3 and use them with the video from title 1, but if 1 actually has chapters but they are not detected, it's probably a bug that needs to be squished.

madshi, what do you want me to do to help you troubleshoot it? Upload a 50MB sample of 00008.m2ts on a website somewhere? Let me know.
