[QUOTE="joecrow, post: 1218780, member: 128337"] I have recently begun to experience green screens very intermittently when watching live DVBT2 HD (HEVC) TV and yesterday evening I also got it with a TV recording. On replaying the recording the green screen always occurs in the same place and is 100% reproducible, it plays quite normally for over 1 hour then the audio makes a machine gun like sound for a moment, the screen goes green, the audio plays again normally but the screen (TV window) remains green, what can be seen of the GUI/desktop desktop display is OK (see screenshot). Using the recording to reproduce the problem at will I was able to prove that the problem happens with both Madvr and EVR, latest and old (pre-2017) Nvidia drivers, a variety of different LAV audio/video settings:eek:. the only thing that changed the problem was setting DXVA2 Copy-back to DXVA2-Native which resulted in an ongoing video stutter, following the problem point, rather than the green screen and unchecking HEVC hardware acceleration in LAV where upon it played through the problem point with only a very short and minor, possible, interference glitch on the video. Not having HEVC hardware acceleration is not for me a solution as it raises my CPU usage to borderline high. EDIT please note the problem can usually be corrected by stopping and restarting TV/recording but sometimes an MP restart was required as screen went black on stop. Any other ideas/suggestions on how to fix this, Logs of a single incidence I reproduced of the problem are attached. [ATTACH]189285[/ATTACH] [/QUOTE]
