Your PC's in one room, and your big, fancy HDTV's in another. How can you bridge the gap between the two? Answer: with a media center extender, which wirelessly pulls music, photos, videos, and more from PC to TV.
Newegg has the Linksys DMA2200 Media Center Extender with DVD for $94.99 with free shipping. These are new units, not refurbs, and they're rebate-free, to boot.
Easy to mistake for a DVD player, the DMA2200 doubles as one. Even better, it upscales your regular old DVDs to 720p, 1080i, and even 1080p. Given that you could easily pay upward of $90 for a standalone upscaling player, the media center stuff is just gravy.
And good gravy, that's good gravy. The DMA2200 streams content from Windows Media Center, the menu-driven multimedia front end that comes with most Home versions of Vista. The end result is akin to connecting your PC directly to your TV--a desirable but rarely practical solution.
The box joins your network via Ethernet or Wi-Fi--preferably 802.11n, though it can do 802.11b/g as well. (Just don't expect reliable high-definition streaming at those speeds.) It joins your TV via HDMI or component/composite video.
Space doesn't permit me to get into all the nitty-gritty on the DMA2200, so be sure to. It's not overwhelmingly positive, but I think that the dirt-cheap price tag makes this a more desirable buy.
Indeed, the DMA2200 originally listed for $350, at which point you were better off buying an Xbox 360 (which nicely doubles as an extender). At $95, it's definitely a worthwhile option for anyone looking to make the PC-to-TV connection.
