 playable? because this looks like eac3to bug with mono thd then, and we
 can close this.

 Yes, the version I first had success with was eac3to v3.31 and I was able
 to demux the thd+ac3 tracks from the source m2ts, demux only the thd
 without the ac3 core, and decode the thd to wav. I was able to repeat that
 with v3.34 today when extracting the submitted full thd+ac3 track. ffmpeg
 handles the track without error as expected. Each file plays back
 correctly.
