if your TV got LAN port, then it should be DLNA Certified, add a NAS to the LAN network and every DLNA TV on the LAN can play the movie resided in NAS hard drive

1) you store your movie files into a hard disk
2) you need a LAN (local area networking) so that every HDTV can access the movie files through LAN, it can be either a NAS(Network-attached storage) or simply a windows or Linux machine which will house your hard dish containing your movie files
3) hook up everything together using networking switch using rj45 cat 5e/cat 6 networking cable
4) now your DLNA compliance HDTV plasma or LCD can retrieve movie files from hard disk through LAN cable and play the movie file right inside the HDTV, no HDMI cable involved

alternative method is using stand-alone media player + HDMI splitter
