https://www.youtube.com/watch?v=7BjTh-PhL4c&list=WL&index=1 is either a playlist (watchlater) or a video (7BjTh-PhL4c). By default such cases are handled as a playlist thus you must provide account credentials with -u/-p or .netrc -n for watchlater playlist. For downloading 7BjTh-PhL4c video with this URL --no-playlist must be passed.

You need to put URLs in double quotes. See https://github.com/rg3/youtube-dl/blob/master/README.md#video-url-contains-an-ampersand-and-im-getting-some-strange-output-1-2839-or-v-is-not-recognized-as-an-internal-or-external-command

I got this error while using 2016.08.24.1 by inadvertently adding an extra character to the playlist identifier. Read the arguments to youtube-dl again carefully.
