I am running Ubuntu 16.04.2 in VirtualBox 5.1.22 and tried to use SMPlayer 15 (I think it was 15, it was the one from the integrated Ubuntu Software application) and SMPlayer 17.6 from their website.
While researching for a solution online I found out about he "Run Mplayer/mpv in its own window" option. But the box for that option didn't have a checkmark and the video still opened in a separate window. So I enabled the option to look if something changed and now at least I have some overlay in the second window so that I can pause the video without minimizing the 2nd window and pausing it with the 1st window. But I still would prefer it if all of it would be just in one window like this https://youtu.be/0QakO8UnUpA?t=212
So any idea how I just run SMPlayer always in one window with all the navigation available?
