I have tried the "try out" version of Clone BD. I thought I would see how it was when converting 4K Blu Ray. I tried converting Top Gun 4K to 1080 MKV 264. The result is fine except for one very disturbing error, a Hue change. This is not a massive change but is definatley wrong. I have tried the competition version and all is fine. (I only mention this because it gives a comparison so as to rule out other things) I also have tried Clone BD some time ago with Blade Runner 2049 with the same results. Can anybody help.
