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!"
I think the "HD Lite" comments are really overblown, at least in my experience. Granted, I only have a 720p projector (Panny AE700) on a 100" screen, but I don't see much of a difference between Fox OTA and the DirecTV Fox broadcast from NYC. That said, I do think HD DVD looks better than both DirecTV and OTA broadcasts.
Maybe I'd notice more of a difference at 1080i, not sure...
