Issue with amperstand (& and &) in the querystring

[BonzoFestoon]

The following works (url in quotes with & and not & in query string):
youtube-dl --verbose "http://savelinkas.net/?p=2590&xink=k1J1YhNklkLeg58oyOL&dmotion=on"

The following do not work:
youtube-dl --verbose http://savelinkas.net/?p=2590&xink=k1J1YhNklkLeg58oyOL&dmotion=on

youtube-dl --verbose http://savelinkas.net/?p=2590&xink=k1J1YhNklkLeg58oyOL&dmotion=on

youtube-dl --verbose "http://savelinkas.net/?p=2590&xink=k1J1YhNklkLeg58oyOL&dmotion=on"

It looks like the extractor is splitting on & to build a playlist maybe?

The output for each, start with what does not work.

That's unrelated to youtube-dl. Your shell interprets ampersands (they advise the shell to start a program in the background). So you'll either pick a different shell (although the ampersand functionality is essential, so apart from DOS, you wouldn't find many shells that don't support it) or escape ampersands or put the whole URL in quotes.
