I have a system that includes: Sony LED 240Hz 3D KDL-55NX810 , and a Yamaha Aventage RX-A3010 Panasonic Bluray (but not 3D) player, and a [*] Sony PS3 (for 3D). All of these components, including my PS3 (which we use for 3D movies only) have hard wired and wireless Ethernet (except for the receiver which is ONLY hard wire, and which we just ordered). The wireless is not always completely smooth and reliable, and with the new receiver having only hard wire, I need to hard wire the system for Internet access and DLNA. So, I bought a 5 port D-Link Gigabit switch for my A/V setup downstairs in the Family Room. My router, cable modem (AT&T U-verse), and computer server are upstairs. I need to link my D-Link Switch (which has all of my AV equipment connected to it, to my Apple Router upstairs. I want to do it via hard wire! I have two choices. I can either use a: new high-end Powerline HD DLP series AV setup, like the D-Link DHP AV 500, that is recommended, or run a Cat6 Cable of 50' between the Router and Switch, but that means having an exposed cable in a number of places The second option does not thrill my wife, because of the exposed cable, but it is easier and much less expensive (I already have the D-Link Gigabit Switch, but would have to get a different switch and receiver and transmitter, about $300, for the Powerline setup). I assume the second option would have a better quality connection. However, I do NOT have much experience with the Powerline HD setups, but they seem to have a good reputation. I would be doing HD streaming of Audio AND video, but do not have a dedicated power outlet (which D-Link recommends). I would have to plug the Powerline unit into an outlet with the computer at the head-end, and into an outlet with the rest of my AV equipment on a surge-protected power strip at the other end. Any thoughts on this? Any experience? I am doing this to improve the wireless performance, so if it won't improve what we have, there's no reason to do it. Thanks.
