I was searching through Hulu, Netflix, Vudu, etc., looking for something to watch. The player hung up on Netflix so I shut it down and when I turned it back on all online services disappeared except for the default Samsung "Connect to Internet" app and photos, music, etc. Hulu, Vudu, Netflix - all gone.
