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!"
It isn't difficult except for those who are unfamiliar with installing computer parts in general. Remember the first time you opened a case to install a CPU or even a hard drive with jumper selection? A bit intimidating unless you had already seen it done or read some good instructions. Hence the value of this video.
This isn't of value for many of us techies, but certainly is for others. A bit more valuable would be a video on how to install a laptop's hard drive in the Popcorn Hour. I was able to, but I've seen a few very technical forums where the question repeatedly comes up, specifically what adapter will fit.
