After doing more searching, it seems this exact was an issue someone reported in the Emby community as well (https://emby.media/community/index.php?/...mkv-files/). The report is almost exactly what I have here. So, it seems that there is something going on with the MKVToolNix splitting that is just tripping up ffmpeg. I am going to keep looking for a solution. Maybe there is a setting in MKVToolNix that will perform the split and not freak out ffmpeg. I am hesitant to use another tool because I finally have solid batch scripts working for MKVToolNix and would rather not have to move to something else.
For those who are curious, I have seen this on DVD and Blu Ray. The Sailor Moon anime series is a good example of this. Each Blu-ray has 5-7 episodes on it. Rather than have all of the episodes split into individual titles, the publisher crammed all of the episodes together as a single title and uses the chapter markers to separate them. For something like Gumby, there was a single title with all of the episodes strung together but there was also each episode broke out into its own title. In a case like that, I always rip the individual titles.
