Firstly, here is the layout of my network; I have used the Airport Extreme/Expresses to extend my network over 3 areas of my house. So... what I am trying to do is to steam Live HD TV content from my Windows Media Center PC to my XBox 360 in another room. Unfortunitly, there doesn't seem to be enough bandwidth to stream the content. If I connect the Xbox to the Media Center PC via a long network cable, it streams perfectly. Would the iPhone being on the Wireless network be slowing down the speeds to G and not N? I would have thought N would have been fast enough to handle HD content. Thoughts anyone?
