With some videos, the d command fails at retrieving information about the available DASH files: all DASH files are listed with "0 Mb" size; only the "normal" audio+video file has non-zero size. So it's impossible to download e.g. only audio files at the desired quality (both d and da commands fail).
Using youtube-dl -F on the same videos, I correctly get all the available DASH files, and I can download the one(s) I want.
