When I play a video, I get a black screen (with any logo overlays visible) with full audio.
If I force close FIreTV and launch Hulu, everything works as it should. Relaunch FiredTV and launch Hulu, I'm back to the blank screen and audio. So it appears to be something FiredTV related.
A Disneyland app also has the same problem when trying to play back video. I get the audio, but no video if FiredTV is running.
This is with the Amazon FireTV Stick.
