To watch satellite TV on your PC with XBMC and MythTV, you’ll need at least one satellite TV tuner card or a satellite provider that offers satellite IPTV access. That Linux TV card hardware doesn’t have to be installed on the same computer on which you want to watch HDTV. We’ll call the computer with the tuner hardware the backend. The computer used to view TV will be called the frontend. The backend and frontend can be one and the same machine. XBMC will be run on the frontend on linux.
