Got my Marantz NR1711 today to hook up to my new Panny HZ980 OLED - 4K performance from the Vero is really nice.
However, as I explored my library, I found an entire series of Dr Who mkv’s that play with sound, but no picture. Couple of playback attempts recorded in the log below. The picture on the first attempt appeared briefly, then went, and the screen was totally blank (no Kodi on-screen controls etc). These have always been fine before. I switched out the Vero for a Pi, using the same HDMI cable and AVR input, and the episodes played fine. I have tried the HPD lock option (I don’t know what it does) but that did not help.
I seem to be a bit cursed with the Vero and Marantz AVR’s at present, hopefully the log will give someone some clues. I tried the special build Sam posted for my NR1603, but that did not fix it.
