Amazon has the Slingbox-like HAVA Platinum HD extender for $86.99, down from its $149.99 list price. The box takes in an HD video signal and streams it back out over your home network via the built-in Ethernet port.
Video on your local network gets compressed as DVD-quality MPEG-2, while you’re also able to watch everything over the internet, too, compressed as MP4 files. The HAVA can also record shows to your home computer for later viewing.
