Occasionally youtube-dl has an error and I've found that a comand-line update of the program updates the certificates and all works again.
cheers
]]>I took GlenW's suggestion this evening and have been playing around in the terminal with the command youtube-dl followed by the URL, successfully managing to download the videos that I wanted (they downloaded as mp4 or mkv files) except for one on the Vimeo site, which downloaded the audio but not the video. However, I found the same clip on youtube and used youtube-dl successfully.
So youtube-dl was the answer to my problem.
Thanks again for good advice.
Maybe there is some kind of web audio codec which does not work when not online - I watch and listen to a video clip in Firefox without any problems, download it and there is no audio with the download. Has anyone experienced and overcome this problem?
