I was watching an episode of the Daily Show when it suddenly locked up. I couldn't get back to the dashboard so I power cycled and tried to watch that same episode again. It locked up again. I power cycled. Tried watching a different show and before the show even started, it was on a black screen that said 'buffering' and the loading ring stopped. Again, I could not access the dashboard. Power cycled again, this time I tried Netflix and it locked up. Netflix and XBOX Live work now after an update but HULU still does not. Please Advise.
