For one I don't think there is a media sharing app from Samsung to do this.

I'm not going to ask you to supply any detail here. I'm going to suggest a word for your research. Good luck, Bob

-> Twonky.

"TwonkyServer makes it possible for your devices to retrieve your media files from wherever they're stored. Using your device's remote and menu system, view your computer's media library, or an online media feed, and just press play.

TwonkyServer is available for Windows?, Mac? and Linux, so it will work for any connected home."
