Okay, I tried to play the above video in ZDMC, but it won't play it. I open ZDMC, then browse to highlight the video, hit the "menu" key on the remote, select "play using", and I'm given two choices: - VideoPlayer (Default) - ZidooPlayer VideoPlayer (Default) - which is the ZDMC player - won't play the video in HDR, and the video locks and freezes up and won't navigate correctly either. So I can't test for how ZDMC handles banding with this file as it won't play it. ZDMC won't play the "LG Chess 4K Demo", which is also HDR, either. Same issue - no HDR, and freezing. So ZDMC won't play HDR?
