如何安装xbmc加载项？

Dear How-To Geek,

I’m a recent XBMC adopter and I have all sorts of questi*** but the most pressing one is this: How do I install add-*** besides the default ones? I see a bunch of cool add-*** when I look in the XBMC.org listing in the add-on menu but I see more cool ones when I search the web that aren’t there. What gives?

Sincerely

Add-On Craving

亲爱的附加渴望，

听起来您已经完成了从官方XBMC存储库安装附加组件的例行程序，您需要做的是学习如何安装新存储库。自从一年前XBMC9.0到XBMC10.0的转变以来，附加组件现在只是存储库。您需要通过官方存储库或第三方存储库安装它们。请参阅我们的XBMC加载项安装指南，并特别注意“从非官方存储库安装加载项”部分。当你在它的时候，点击XBMC用户论坛上的新的和有趣的附加组件吨线索！

我怎样才能缩小**的视频？

Dear How-To Geek,

I have a bunch of videos on my computer but they’re all 720P or higher quality. I’d like to put these videos on my phone to watch on the commuter train every day, but it seems really excessive to put an HD video on **all phone screen. For that matter, I’m not even sure if my **artphone would choke on the HD content. What can I do? Surely there has to be a simple way to “downscale” the video or something!

Sincerely,

Video Commuter

亲爱的视频通勤者，

移动电脑时如何更换打印机？

Dear How-To Geek,

Both my actual office and my home office are pretty much totally Wi-Fi based, including printing. It’s a huge pain to toggle settings based on location. Is there anyway to have my computer just figure this crap out on its own? It’s 2012!

Oh, I guess you need to know about my actual computer, eh? I’m running Windows 7 Professional on a fair mundane Dell laptop.

Sincerely,

Check Twice, Print Once

亲爱的支票两次，

幸运的是，Windows 7 Home上的Windows 7版本支持根据计算机连接的Wi-Fi节点切换默认打印机。您可以为您所在的每个Wi-Fi打印环境（家庭、办公室、学校的计算机实验室等）设置默认打印机点击本指南了解如何将打印机链接到Wi-Fi网络。
