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!"
WMV is one of the BEST formats out there. Even better quality than DivX. And is the format used most promently in HD-DVDs. The Xbox360 is in fact superior and more capable, and come the spring update will also be able to play more video formats than just WMV. I always use WMV for encoding compressed 1080p and 720p video, and it looks amazing. Just because WMV is used doesn't mean that that it has to be DRMed. All the WMV I encode myself is DRM-free.
But to stay on topic, I'm dissapointed with the limiting codecs on the AppleTV. It could be so that they can be able to stream all over n without risking hiccups, just so that it "just works". It's just apples strategy, I suppose. But I wonder why they didn't just add more codec, high bitrate, support, and just limit what videos can be watched based on the connection. Like if you're on wireless, you only get what you're allowed now, if you're connected via the ethernet you can watch more. Well I guess that would just add more confusion to people that don't get why they can't watch everything over wireless. Since Apple is going for the overly simplistic, you get one option, and it's not your best but it "just works" and you pay through the roof for Apple's style. I guess it's working for them, but people like us wouldn't waste their money on something so limited. I guess they musta figured out that enthusiasts will get what they want out of it themselves.
this wmv vs. mov vs. avi stuff is pointless. mov and avi are container formats, so they will always be as good or better than wmv.
