“One of the great features about SMPlayer is that it
has a configuration file in which it saves all the settings,
separately for each video, including the remaining time. So if you
close it then re-open a movie later, all the settings which you’ve
set for it will be automatically loaded, and the movie will
continue from where you left it. This does not apply yet to DVD ISO
images though.”
