Since I did to read, here's translations:
Post 1....Is the Anthem AVM 70 compatible with Netflix? My answer: Can't think of why it wouldn't be compatible. Why do you think there would be a compatibility issue with a streaming service, let alone a particular one?
Post 2....I had the new Anthem AVM 70 and my three MCA 525 amplifiers plugged in by a professional installer. I only got Dolby Atmos on Netflix once. As I was too tired I did not watch the films which were displayed in Dolby Atmos. The next day I was no longer able to have a single Dolby Atmos movie. What should I check to get Dolby Atmos? Please help me! -- My answer is that if you got it once, it works. Not everything is available in Atmos on Netflix so it may have to do more with your choices to watch?
