"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!"
My 1080p's scaling works good from 1080i to 1080p, or 720p to 1080p, even 3:2 sources in 1080i or 480i. The 480i to 1080p upscaling is decent, not great, but my ps3 upscales DVDs to 1080p and does a great job. I just don't see why anyone would need this. Nearly every HDTV upscales any resolution to the native resolution. Waste of money.
