I tried it with my Sony Network Media Server and it worked! It's a neat little box, similar to Apple TV or Roku, that connects to your WiFi network and streams just about anything from your PC or the internet, it has the PS3 like UI. For those thinking about buying the HTC Media Link, the Sony Network Server is only $50 and does full 1080p like the HTC plus a heck of a lot more stuff, including native Netflix, Pandora, Hulu, Amazon video and music and a bunch of other "smart apps".
The only think it wont do is the multi-tasking that the HTC Media Link HD allows, now that is awesome! I might pick it up just for that.
