way to stream Netflix. You could just get a Roku box for 100 dollars if budget is an issue (you will need an ethernet connection or a wireless adapter though). Some players (like the LG BD 390) come with built in wifi adapters for connecting to a wireless network. Amazon has that one for $260 right now.
I have found however that Netflix streams a lot more reliably (even in HD) when you take the wireless netkork out of the mix. Since my living room also has an Apple TV and an Xbox360 I decides to move my router and cable model to my entertainment center and hardwire all of that equipment and let my desktop and the laptops be the only devices using the wifi network. It works beautifully.
I know I'm going to buy a Bluray DVD player able to accept Netflix. Computer and HDTV are in separate rooms and hard wiring too difficult so I'm thinking of Belkin or other brand of Powerline adapter? Do I need a router since I only have one PC? If so, wired to hook into the Powerline adapter or wireless. The TV is HDTV but not ready to accept Netflix.
