I couldn't find the difference between the free version of JRiver and the paid version (maybe I didn't try hard enough), so I opted for the paid version. However, it seems that the video on a popular free player is better than what I'm seeing on JRiver. I'm only interested in playing 4k UHD Blu-ray discs, not ripping or anything else, just playing the discs. I have a 4k friendly drive and am using MakeMKV, I have a new Lenovo 9i laptop with a 4k OLED screen. Playing the discs isn't a problem but I am concerned about why the video seems better on the free player. Am I missing something in the setup with JRiver?
