HDTV over WiFi: 802.11a helps – HD Beat: HDBeat was out previously with an article saying that they were less than impressed with their ability to stream HDTV from their Media Center PC to their new XBox 360 Extender using the default shipped 802.11b. They now have installed an 802.11a wireless router though and say it works much better. Nice to know that this is an option but I’m still going with ethernet when I finally get mine.
