Hi!
Thank You for very helpful Post. I thought I could skip jrss mixing. that this made the subwoofer react diffently. but this is not so and it is necessary to give stereo output, since all movies are surround. I also got confused since i got stuttering in movie play. I found out now that the soundproblem was imbedded into the moviefile. Unbelievable! I was sure that something was destoyed. But it was the movie file. I use the alien movie covenant. and I downloaded it in both 1080 and 4k . and both had the same problem. when I tried it on my fahters laptop one could hear the soundproblem(high light sound from wind instrument) reproduce itself there also but less audible, but it was there. So that was a rear incident. never come across before a movie that had soundfault imbedded in the file(I tried 4 different versions/files). I became blind thinking there was a soundproblem after everything changed(accident) after enabling 120hz most likely(maybe the graphic card overheated and then it happened).
Also my pc freezes sometimes not even ctrl alt del work. it freezes completely. I have never found out what causes this, strange.
On your 2) recommandation. the rendering was better. this is a new feature. I just tried it. It was very smooth. Thank You. I also tried hdr(ticked both 'passthroug hdr'(this did not activate hdr play of the movie) but when I ticked 'os hdr support' then it played hdr, but I did not like the picture. to saturated and oversharp settings(look similar to lcd picture, I like more natural looking picture)
and to use 'automatic change mode' in displaysettings. I am not sure how to use this. I just choose to turn it 'on' but I did not see any changes (ctrl + j , picture shows in 59.99hz). I don expect you to show me. I have to find out myself. But thank You for showing me this. Generally I find it hard to find out how to use J River. Now that I see the how good jrvr I certainly will found out more about it.
update! I had to choose jrvr because it gave the best result. but I still got problems..the picture stops and pixelate. But Jrvr was better but still problems. It looks like this happens when I play from large files like 50 gb. Are ther any way to change settings in jrvier and jrvr to solve this?
Thank You for helping me, Terry!
