Yesterday for the first time I couldn't hear the sound properly. The music and background tracks played fine, but none of the dialog did. This coincided with the app on the Apple TV having been updated, as evidenced by the app logo now saying Netflix in red on white, instead of white on red, as before. Netflix tech support had me turn off Dolby, which made the voice track come back. We have had no such problem with movies played from the iTunes store. I am wondering, whether there are others who have had this issue.
