Hi everyone...I'm thinking of joining Netflix, but I want to be able to stream the content from my computer to the TV in my hall. I've been told that Apple TV will do this. Is that true? I have an older iMac - early 2009. Which version of Apple TV will I need. Also, I don't have the best whiz-bang internet connection. Will I need a really good speed to get a good picture without it buffering endlessly? And if so, what kind of speed will I need? Or maybe I'll have to hardwire the TV into my modem/router? Thank you!
