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!"
While I'm a fan of SlySofts AnyDVD, and will upgrade to a HD version whenever I decide it's safe to choose a format... I couldn't just let your HTPC comment slide.
I've only been using AnyDVD for about 6 months, but have had my HTPC running on a DVI-HDMI cable for almost 2 years, and watched movies on my old analog TV via S-Video before that, all on XP... I don't know where your specific hiccup originated, but it wasn't XP.
Anyway, this is great news, hopefully a BD version isn't too far behind.
