Re vc-1, as I already asked, isn't there a built-in player inside the FTV you can try them with?

The FTV does not have a stock video player as you would expect from other Android offerings. There is no movie/video player installed by default. The only way to play content on the FTV in its stock form is to stream it from Amazon or another App available in the store. When I open a video file in ES file explorer, I am only offered apps that I have side-loaded. The stock picture viewer shows up as an option, but as expected does not play anything, even local pictures don't load on it.
