I currently I have a Satellite HD DVR in 3 of 4 rooms and a standard receiver in the fourth room. I'm considering replacing the satellite service with an antenna + internet combination. My idea is to run the antenna to a Mac Mini and use the Mini as the DVR and internet TV source. My question is is it possible to distribute separate video from the Mini to the different rooms or would I need to have a Mini dedicated to each room? Thanks in advance.
