-The links provided by youtube-dl -g are not working anymore
+I extracted a video URL with -g, but it does not play on another machine / in my webbrowser.

+It depends a lot on the service. In many cases, requests for the video
+(to download/play it) must come from the same IP address and with the
+same cookies. Use the --cookies option to write the required cookies
+into a file, and advise your downloader to read cookies from that file.
+Some sites also require a common user agent to be used, use
+--dump-user-agent to see the one in use by youtube-dl.
+
+It may be beneficial to use IPv6; in some cases, the restrictions are
+only applied to IPv4. Some services (sometimes only for a subset of
+videos) do not restrict the video URL by IP address, cookie, or
+user-agent, but these are the exception rather than the rule.
+
+Please bear in mind that some URL protocols are not supported by
+browsers out of the box, including RTMP. If you are using -g, your own
+downloader must support these as well.

+On Windows, how should I set up ffmpeg and youtube-dl? Where should I put the exe files?
+
+If you put youtube-dl and ffmpeg in the same directory that you're
+running the command from, it will work, but that's rather cumbersome.
+
+To make a different directory work - either for ffmpeg, or for
+youtube-dl, or for both - simply create the directory (say, C:\bin, or
+C:\Users\<User name>\bin), put all the executables directly in there,
+and then set your PATH environment variable to include that directory.
+
+From then on, after restarting your shell, you will be able to access
+both youtube-dl and ffmpeg (and youtube-dl will be able to find ffmpeg)
+by simply typing youtube-dl or ffmpeg, no matter what directory you're
+in.
+
+How can I detect whether a given URL is supported by youtube-dl?
+
+For one, have a look at the list of supported sites. Note that it can
+sometimes happen that the site changes its URL scheme (say, from
+http://example.com/v/1234567 to http://example.com/v/1234567 ) and
+youtube-dl reports an URL of a service in that list as unsupported. In
+that case, simply report a bug.
+
+It is not possible to detect whether a URL is supported or not. That's
+because youtube-dl contains a generic extractor which matches all URLs.
+You may be tempted to disable, exclude, or remove the generic extractor,
+but the generic extractor not only allows users to extract videos from
+lots of websites that embed a video from another service, but may also
+be used to extract video from a service that it's hosting itself.
+Therefore, we neither recommend nor support disabling, excluding, or
+removing the generic extractor.
+
+If you want to find out whether a given URL is supported, simply call
+youtube-dl with it. If you get no videos back, chances are the URL is
+either not referring to a video or unsupported. You can find out which
+by examining the output (if you run youtube-dl on the console) or
+catching an UnsupportedError exception if you run it from a Python
+program.
