If you're going GPU to AVR to PJ, and your AVR isn't listed, you have a problem.  No idea why you have to put madVR folder in MPC folder?  I just have mine in Documents.  It sounds like you are installing/uninstalling madVR by using the two .bats inside madVR correctly.  I would backup 'settings.bin' file (this is backup you can replace later), run 'restore default settings.bat', 'uninstall.bat', delete the contents of the madVR folder, reboot, turn on the AVR and PJ, unzip the latest madVR back into it, and then 'install.bat' and see if your AVR shows up.  Also, did you leave Lav Filters default?

First of all merry Christmas to everyone
I did exactly as you described it and still the AVR is not shown in madvr. I only see my projector. All my devices (PC, SATV, PS etc.) are connected to my AVR and then my projector is connected with hdmi to my AVR.
In Lavfilters I set the settings as you described in post 205. I also tried to reinstall lavfilters and leave everything at default. Didn't change anything.
But when I am understanding

Correctly hdr isn't working correctly with Nvidia until now or am I mistaken? Maybe only inside kodi with your .bat and player factory?
