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!"
First, I do like HD-DVD better than Blu-Ray. However, if HD-DVD movies cost less to produce; why are these movies just as expensive as Blu-Ray? One would think that HD-DVD titles would cost much less. I guess everyone wants to screw the consumer.
The price of the discs is close enough in production that you won't see a large difference in cost. Combo discs may get cheaper in the future but that depends on how many studios are pressing them.
