This video is showing a know problem with Dolby Vision and certain players (Firestick, Shield TV, etc.) and certain TVs. This problem is not the AVR. There is not enough information given in that clip to know. What version firestick, what TV, is the video be streamed from Plex or some other source. Another thing to note is why does this person have Enhancer on with Dolby Atmos\/DD+?\n\n\nIt has nothing to do with "certain players". It only happens with the new Yamaha AVR, whenever Atmos via DD+ (not lossless via THD) is played and AI\/Enhancer are enabled. It will happen on ALL movie streaming services such as Netflix, because they can only use DD+ for Atmos. it does not happen with Blue ray playback, as it uses True HD. This was confirmed by many users at AVS as well.
