We have our Ceton InfiniTV working great on the HTPC in the family room, and are now looking to connect the system to XBox extenders in other rooms in the house so that we can watch live shows and/or stream recorded programming.
For various and sundry reasons, we are not interested either in wireless technology or in tearing down walls to run Ethernet cables around the house. Therefore I've been looking at three other possibilities for networking our devices: powerline (such as HomePlug), phone line (HPNA), and coax cable (MoCA).
Which of these options would provide the best and most reliable signal? I've heard that powerline networking (for instance) is affected by dimmer switches and appliances putting out "dirty" signals? We would like the network to be capable of sending out programming in 1080, high-def resolution.
In case it makes a difference to the answer: our house is fairly new (1996) and we are on cable (not satellite) TV.
Thanks in advance for any advice/info/tips you might provide.
