I found these settings on another post
RPi4 no video unless forced hdmi mode over SSH
Add the changes to config.txt. I'm not sure which setting made it work.
hdmi_mode=16
hdmi_group=CEA
hdmi_drive=2
I edited the config.txt on Windows, placed the chip back into the PI4 and rebooted. DVD Video works great now.
I have experienced the same problem. I have ripped DVDs to DVD files and when I play under KODI, I get audio only, black screen. I have tried both HDMI ports, 2nd HDMI port did nothing. Not even audio. I have done a lot of research and can find nothing related to PI4 on LibreElec and not being able to play DVD files until this thread.
I debugged KODI, and I see the selection of the mpeg-2 video, but it's just not working. I play these same files on the PI 3B+, no problem.
