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!"
No mention of the software for other then windows... of course. Would really love it for OSX.
I actually gave up on a Mac/TiVo video solution (TiVo Desktop for Mac is still sharing my music out) after Roxio completely flubbed the details from TiVo's fall 2007 update. I, amongst others, was left waiting for a month before we could have a decent TTG solution on the Mac again.
So, I threw up my hands in defeat, went and bought a Compaq with Vista and it's running as a TiVo server (headlessly) on my network. And that's all it does.
Check out pytivo. It's an open-source alternative to Some tinkering required, and it's not perfect, but it will run on anything that has python & ffmpeg (both of which are available for your mac).
