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!"
BTW, the version that aired on the NBC west coast back on the 13th was broadcast in 1080i.
I was pleasantly surprised that it was in HD.
It is about 4.5GB with commercials edited out. :)
