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!"
Yes, I agree with the other comment. PowerDVD DROPPED the ball on HD DVD support with their cyberlink powerdvd 8 ultra version. At least Arcsoft TotalMedia Extreme is supporting the HD DVD format with their newest version. Thumbs up for Arcsoft. Plus it is less $$$ than the Cyberlink offering. I have experimented with it and with it's latest update (you have to do the update after downloading and installing it), there is HD DVD support and ATI support for XP users also now. I'm still having issues with flickering, but at least it is recognizing the HD DVDs and playing. I may have too slow of a cpu with the Athlon X2 3800+, which is not on their list of recommended CPUs.
