Best way to do it with the highest quality is to buy/borrow the movie. I say that b/c most movies you'll find to dwnld will have already been dramatically reduced in size. Consider most dvd movies take up b'w 6-8 GB & you dwnld a movie less than 1 GB or less than 700 MB then how much quality do you really expect. Watch it & toss it! It will have already been reduced in size so much I'm sure it won't look 'that' great compared to the original on a TV in particular! (but then again the ways the average non-digital tv works maybe will have a smoothing/almost blurring fx that'll trick the eye!) You deinitely won't need to reduce it in size & wouldn't be recommended.)
