Add "ActivateWindow(123)" to your keymap and you can adjust many settings with your remote. These settings are saved in the madVR control panel.

And select "Load from madVR active profile" for the least hassle with madVR settings.

 Cheers Warner,

I am a little confused about what you meant by "Add "ActivateWindow(123)" to your keymap and you can adjust many settings with your remote"

I am almost ready to give up on the whole FSE issue, however if I'm not mistaken I currently need it to get the best out of my HDR material. Is that correct?

As I mentioned before, the curious thing about this issue is that FSE works everytime with MPC and maybe 1 in 10 times with DSPlayer, so I don't think there is any issue at the MadVR end, otherwise it would never work. I do feel like there must be a conflict going on here somewhere and I'm inclined to think it's at the Kodi/DSPlayer end.

If I'm loading from the MadVR active profile, do I need FSE selected in both MadVR and DSPlayer settings, or does one make the other redundant?

On a slightly different note, do you have your Kodi open at all times or do you open and force close it from your remote? I've struggled with reliable ways to close Kodi from the remote recently
