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!"
Charter Digital in Worcester, MA (and I'd presume the surrounding area) seems to have recently added 734 A&EHD, 735 HISHD, and 742 MOJHD. I caught an add for MOJO HD on another channel, and found the others when I looked at the lineup.
TMS seems to still be missing them - Zap2it.com, TiVo, etc, all lack guide data for them.
