I've just got a Samsung DVD player that has an Internet@TV . Samsung provides and SDK to develop your own apps for their tv platform. It's basically a Maple browser with some plugins for handling steaming media. I thought maybe I could port subtunes, since it says it's pure HTML, but it turns out it's full of flash.
If there's a pure HTML player for subsonic, even if it's very basic, that would be a good starting place for me. Any suggestions?
