Let the hive mind of Engadget get that for you.
"What is the best wireless surround sound speaker solution? I have a home theater where running wires is just not feasible. I have my own speakers, so I don't want a system that has speakers with integrated wireless. I've done a far amount of research and have only come across a few companies that even offer a reasonable solution: KEF, Kenwood and Rocketfish. Is there anything else out there? What do you recommend? Thank you!"
Is this gong to be a HD XBMC ???
What do you mean?
Nothing XBMC does will make the classic X-Box handle 720p x264 vids smoothly, but XBMC can certainly output HD...
Yes, XBMC supports HD on non-Xbox platforms i.e. Linux, Windows and Mac OS X. If you have a fast enough CPU and a decent graphics card, you can play most of your 1080p content in XBMC.
