Every afternoon at lunchtime, I have a problem. My wife wants me to download a TV Film while I'm working on the computer. The process is always the same: download it, search for a pendrive, plug it, copy the TV Film, Search the USB connector behind the TV with skill, play the video.
All this can be done to saving my time, running on my Raspi DLNA service compatible with SmartTV and AllShare. Now I download the TV Film, run the DLNA on the Pi and... Done!. DLNA system is also available on mobile devices like Android or iOS.
I just read a very clear tutorial explaining how to install it in a few steps on your Pi or any other Linux computer. I really worthwhile.
