Hello,
The problem turns out to be a poster thumbnail inserted as data. A closer look shows the thumbnail listed in ffprobe. I removed the thumbnail and the problem was removed as well. Problem solved. I'm not used to this forum format so may have not recognized your response in a message that seemed all junk. I incorrectly assumed ffmpeg, VLC, and MediaInfo recognized the full set of Matroska and MPEG-4 tags, except, maybe, for the custom tags in the Matroska specification. Thank you for your time and interest. Jim Julian Cogito ergo sum. René Descartes circa 1685 “I think, therefore, I am.” Sum ergo cogito.
