Good shout, sorry didn’t even think of that as all my HDR stuff is on a separate disk.
Yes, non hdr videos play fine with drmprime.
I’d still like to wait for someone else to test just to rule out my setup - or me doing something silly
I can confirm that I get exactly the same as PlatypusW.
I was able to config my audio to pass-thru 100% properly.
I played a 720p x264 file no issue with video on screen and DTS audio.
I played a 2160p x265 file and got DTS:MA audio out of my speakers .. the TV transitioned into HDR10 mode .. but I got no picture, just black.
I will say though, progress on the tv switching into HDR10 mode .. woohoo.
