Hello Gents,
I am relatively new to ps4 after spending 8 years with ps3.
i am absolutely shocked with the fact that we cant copy movies downlaoded from torrents to our ps4 system and watch it there.
i do have a bravia hdtv which supports usb movies playback but as i keep movies on my ps to watch it later again and again if my mates come over or cousins.
the only bit i could find was PLEX TV service.
its a free service, all you have to do it on your laptop download the PLEX app from PLEXTV.COM website.
it will open your internet browser after installing and select the root folder where you have movies in your computer.
not goto your ps4 browser and open plextv.com and sign in with your account( free to make)
and this way you can stream all your movies from your pc to your ps4 system. this service is totally free.
plex media player on ps4 browser is really good and it plays the same 1080p video or 720p video quality whicher the quality you have in your computer.
try it. if you have any problems let me know i will be happy to help as i learned how to use this service the hard way 
i am downloading Infamous for free these days as it came out yest on ps store for ps plus members.
i have a 7 years old UK PSN account and i still use that, bought ps plus membership card valid for three months for 2100 rupees for uk region account from http://www.maximuscards.com/ website. and they emailed me the subscription code asap and i redeemed it on my ps4.
bear in mind that i made the payment to the website for psn plus code from my islamabad, pakistani bank card.
cheers big ears.
