As its asked so often I'll keep it brief. 4x4 matrix with one output being a media player. Rest of house to be smart tvs wired to cat6 network. Will have a 4tb NAS and hope to install PLEX thingy do dah. Many movies and TV series stored on here in MP4 or AVI with a few also in MKV Will have Roku 3 as media player (possibly being controlled by Control 4 system remote in living room) which is then accessible at any of the 4 outputs from matrix. Remaining Tvs if they have PLEX will have access to same content as roku3 Will this work and is this the best solution? I dont really want a PC or other extra unit running all the time.
