I've used a TV to play DVD's and free streaming before, from FreeBSD and HDMI. No one has mentioned Blurays on FreeBSD in a long time. There were few mentions that it worked on a future version, and latest media player. Then, after that, I didn't hear about it anymore, and that was years ago.
It's ok, but sometimes, I want to use the remote, not keyboard, or the screensaver comes on sooner in the middle of a movie/show. Or, I don't want to be distracted by the desktop, and only watch movies/shows/streams. A desktop is also more limited than a Roku Stick, bc it has its own free content, and other free content won't play on FreeBSD.
They want to set up a streaming media server. I would like to see examples of that, and that compared to other ways.
