Hello,
Thanks for the answers.
Red October Standard seems to be working, but I would like to use "my" madVR settings.
Yes, after "fiddling" madVR settings (according to a tutorial and which has been working previously in Kodi and in JRiver as well).
I am trying to play my collection including: SD, HD, 4K, 3D videos. Some of them are in mkv format, the others are in iso images.
I have experienced other effects in JRiver previously: permanent green flickering during video play. After I have switched my LG 4K TV to "Deep Color" HDMI input the green flickering
went away. Afterwards, I made my own profiles, settings in madVR. Then JRiver "crashes and needs to be closed" right after I start playing any of the videos (regardless of SD, HD, 4K, 3D), however, they should be rendered a bit differently using my own profiles.
