I look in there too along the stream LK pages.
in a normal screen, there is a bar right top ---> download this video
for full screen, double click on the screen

if you click, it starts downloading the part you want.
stop when you want, click next to the current bar

for setting the time, how long you want, see the example / hand

the movie you can look back in the folder, real player downloads.
when looking back can use the button, playback speed to 16x speed -->see the arrow
