In most (all?) BD cases these chapter marks fall exactly on the first frame of a new scene.

I'll do some further research and see if I can find some additional info on some of the BDs I have.
@SomeJoe, if you read laserfan's post, it seems that in his experience most Blu-Rays seem to have proper chapter marks (at least when using h264). I tend to agree with you that if 1001 is needed, it's probably an authoring error.

Eac3to does create the all the files requested for the first file but seems to quits when it sees the second file 00000.m2ts that contains the DTS-HD track. See my screen shots from MediaInfo posted above.
Which movie is that?

Please drop a comment here whenever you see this problem. Maybe we'll have luck and I have one of those Blu-Rays myself. However, I've not really stumbled over this problem myself yet.

Not sure myself where the problem came from, but the eac3to you're using is pretty old.

I think that's the only speaker combination which makes problems. At least the only one I'm aware of.

The Haali MKV Muxer (which eac3to is using) does not support the right eye stream format. So that's why eac3to cannot mux the right eye stream to MKV. mkvmerge currently doesn't support it, either. I've already given Mosu (the mkvmerge creator) all the information he needs, but he says that it's not a high priority for him currently. There's not much else I can do here...
