I am totally overhauling my home cinema after 10 yrs in the dark with my pre-HD Panasonic viera and pioneer VSX av reciever. My intention is to have the Panasonic Veira 50GT plasma, Yamaha RXV 673, a new Sky+ HD box and my current Panasonic Blu Ray player, my speakers will stay the same. Whilst I know that 3D Blu ray players can upscale my old DVDs to simulated 3D on the Panasonic 50GT, would the Yamaha RXV 673 be able to upscale my DVDs from my current DVD payer to my 50 GT or do I need a 3D Blu ray player? Also the Thatcable HDMI with ethernet claims to connect two devices to the internet when only one of them maybe WIFI enabled, does anyone know if this can be more than two devices e.g. can I connect the Sky+ HD box to the internet, via the Yamaha RXV 673 which is receiving the internet from the Panasonic 50GT's WIFI?
