Description of your issue, suggested solution and other information

fails to download that url

[dstftw]

You are using an outdated version of youtube-dl. Read this FAQ entry if you have troubles updating.

But that's bizarre I first downloaded youtube-dl yesterday, and then I downloaded this:

youtube-dl-2016.08.13.tar.gz

and extracted it and ran the script directly - but I can see now that you mention it that it does give an old version number ... what could be going on???

[vec-perm]

It's not that there is some sort of updating that has to be done before you can run it?
my script just does
python -m youtube_dl "$@"
where the youtube_dl is the thing extracted from youtube-dl-2016.08.13.tar.gz

hmm, clearly it is actually picking up the system installed version - apologies for the noise.
