Now that I have a reciever,blu ray and HD dvd all with ethernet capabilities for downloads and firmware updates,I need a switch,game extender or router????? to hook up to my single network cable connection, I have avaliable to my HT system.What I do now is move the network cable to the device I want to download to,which is a pain.What manufacture and model should I use so all my components can access the network when they see fit or if I want to download firmware updates.Any reccomendations?I do not need wireless as I have a network cable avaliable.
