can you be wired for the internet and not be involved with "blue ray"?
Yes you can be wired for Internet, but you need to still get the Netflix to the TV's somehow. The device has to "support" Netflix, in other words will need to say "Netflix" Capable right on the device in order for you to get Netflix.
So you need to purchase "something", anything that supports Netflix. A PS3 game console, a blu ray player, a Wii game console, etc.
