When it says Be sure to call youtube-dl with the --verbose flag and include its complete output. it means to add the --verbose option, not --verbose flag ;).

I can download them, just run it a second time and it may work (it's the only solution right now). If it still fails, we'll try to reproduce, thanks for the report.

Yeah, YT is playing with different algos. Sometimes it comes down with algo no. 83, sometimes with 81. If I catch it again I'll rerun with the correct parameter :).

Ok, I'm closing this now, but if you discover a video that always fail, please comment here or open a new issue.
