I scaled it back to 10 bit 4:2:2 just to check. The problem recurs actually only after a dolby vision file plays. when we hit stop on a dolby vision file, the box switches back to REC709 and only plays that. Colors are predictably wrong on HDR and SDR files. Dolby vision files trigger a reseync and rtuern to BT2020. The only way to get SDR and HDR files processed through VS10 again is a reboot. What setting do we think I’ve got wrong that’s turning off the VS10 engine after a dolby file plays?
