Description of your issue, suggested solution and other information

I've setup ~/.netrc and have it works fine with wget, but not sure why it doesn't work with youtube-dl, it seems youtube-dl fails immediately upon the 401 auth error, without even picking up my .netrc file, even though I've specified the -n option. If I use -u option to provide the username then type in my password interactively, it just works.
