Ok, this is somewhat of an offbeat post for me but stumbled uppon this and thought it was really cool. I don't use a HTPC (Home Thrater PC) at home right now mostly because sich a solution would only make sense for me if my TV provider (DirecTV in my case) didn't provide me a HD DVR. And to get coverage throughout the house, I would essentially need a PC (or maybe just an Xbox360) for each TV I wished to connect. Can get expensive real quick. In the best of worlds, I would have a single HD DVR in the house, which may not even be physically connected to a television, and then each television would pull content from the DVR.
The new Extender for Windows Media Center was launched last week and from what I am seeing, it is definetly a step in the right direction (you can get general details here: http://www.microsoft.com/windows/products/winfamily/mediacenterextender/default.mspx). I've listed below some of the main partnenrs and the components they are releasing. The offerings come mostly in various flavors of network ready set-top boxes. But I have to admit I really love the offering by HP where they essentially included the technology directly inside of their new 1080i LCD TV's. I have to admit I am really tempted considering that my current 50" plasma, at ~5 years old, is starting to show its age...
