@TopazHarley from your log

[debug] youtube-dl version 2016.02.22

[TopazHarley]

@dstftw
toppy@serena ~ $ sudo youtube-dl -U
youtube-dl is up-to-date (2017.01.14)

I originally installed from Mint/Ubuntu repos, then used manual install from GitHub ... let me remove all and start over :-)

[TopazHarley]

@dstftw
thanks Sergey, that fixed it .... repo istalled to /usr/bin ... manual install installed to usr/local/bin so it did not update to latest version
thanks for the help
