Why can't my Samsung Link play movie files from my pc straight to my Samsung TV?

[AC Question]

samsung link cannot play movie files from pc straight to samsung tv

when i was using the galaxy s4 i would select a movie from my pc to watch on my mobile, then i would press the "send to tv' button and watch it on the tv. now with S6 i cannot find this function, the movie needs to be uploaded to the phone before i can "share" it to the tv
