Has anyone had problems with Pana 820 and 2001: A Space Odyssey UHD (UPC 883929671526 reissue with red UPC label)? I have encountered pixelation at about 1:16 and both video and audio stuttering starting at 39:00-41:00 and 1:15-1:17 and sometimes losing audio totally. This happens with all soundtracks and AVR codecs. Pausing or rewind Pana for a short time mostly help but not always. I thought of player or AVR overtemp but cooling them did not help. All HDMI cables are 4K and 18 Gbit/s certified. Player outputs HDR(PQ)/BT.2020 YCbCr 4:4:4/12bit. This with Auto setting. AVR and Player have latest firmware installed.
I could not see any damage or dirt on disc surface.
