SnapStream adds placeshifting to BeyondTV PVR software
But the latest beta version of BeyondTV adds a nifty placeshifting feature utilizing Microsoft's Silverlight technology. Users can login to the web administration interface for their accounts to see a list of recorded programs. In the options menu is a button that says placeshift. Click it and BeyondTV will analyze the recorded show and your internet connection and transcode the video in real-time for streaming over the internet.
In other words, if BeyondTV is a TiVo killer (for ubergeeks who would rather build their own, anyway), BeyondTV 4.9 beta is a Slingbox killer (again, for the ubergeek set).
BeyondTV is available for $70 or you can download a free trial version.
