Replying to saving line vids

so i want to be able to save the vids from the line site to my comp so that i can always have them, and so that they wont have to load every time. this way if they change the site i will still be able to watch them. i have tried many things and cant find a way to save them. when i click save as it just save the pic, not the movie.

if anyone knows how please tell me. thanks.
