I’m having the same trouble with Vegas Pro 12. Trying to use the file as input to Architect 6.0.
I “render as” Main Concept MPEG-2 -> DVD Architect NTSC Widescreen Videostream.
Saw a youtube video that showed a file created with “Movie Studio” using chapter markers came into Architect with the markers showing up.
I see there’s an option in Architect that allows you to “insert scene/chapter marker”, but I hate to have to redo it (have 30+ chapters).
Thanks
