I currently record TV shows on my personal computer and watch them later on the living room TV using a Ceton InfniTV 4 card. I wanted to be able to watch the shows on the bedroom TV so I ran the RCA cables to that TV and was successful. However, it's not the most popular method having all the wires running across the floor and doors as you can imagine. Does anyone make an adapter like they have for networks that plug in the wall and transmit through the house on the existing wires? Thanks in advance Dave
