Since this is an ongoing problem for some owners and not others, there must be something in common between these owners. I know I've not experienced any Black screens, and no audio dropouts either. We've watched about 5 DV titles, and 4 HDR10 titles without experiencing any issues, except one instance where I heard a low static pop sound in a Soundbar at a point in a movie where another member had an audio dropout. I only heard the pop sound because I was checking the audio at the exact spot reported by the other member. If I hadn't been watching the playback timer and listening intently, I doubt I would have even noticed the pop.
To be clear, I'm not doubting anyone else's experience, but I'm still thinking that some* of these issues are related to individual setups, based on the equipment, including cables, and settings being used. (*I used "some" because I know K is working on fixes that are more universal among owners).
