I have my B6 OLED on the latest firmware since it came out early May.
All of my movie content yesterday stopped working...all of them. Amazon, HULU, Netflix, Google, YouTube, VUDU: none of my movies will play. When you start a movie, I only get the initial loading and then most of the apps just a blank screen with nothing else occurring. In the Netflix app, I can get a progress display slowly up to 25% and then it stops. In Google and YouTube, I'll get a not authorized to play this content message. But while still in YouTube, video content plays fine; just my movie purchases won't play. It's not my internet as the same apps play just fine from other devices and I have a 85 Mbps download.
I haven't reset the TV yet as I wanted to see if anyone else is having the same problem before I have to go redo all my custom video settings and reinstall apps.
