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!"
Region coding is a tool for a studio to control releases to home markets while the movie is still in theaters, Newline has so far been very concerned with this and for a valid reason, so that imports don't compete with theater ticket sales. Only people I see having a major problem with this are those that buy an import and/or HDDVD owners who have to wait until a later release date from Newline....
