Got me a U9-H a while ago and it’s working almost flawlessly, apart from an occasional 4K HDR scene with very high bitrate. In Kodi the image freezes, sound continues and after a few secs image pics up again and everything is resumed perfectly. I’ve tried everything I could think of but nothing worked 100%. I made a short clip from a scene on which it chokes for anyone who would like to try it. The clip plays perfectly on my Windows machine. (I can't post the link yet, since this is my 1st post on the forum) This is what I tried so far: I must have read every thread on stutter, buffers, cache, etc… In Kodi 17.6 I think I’ve tried every setting Playing either from network or USB drive doesn’t matter Using these settings in Advancedsetting.xml doesn’t change anything: <buffermode>1</buffermode> <memorysize>209715200</memorysize> <readfactor>10</readfactor> Kodi 18 Leia, the same problem SPMC is an improvement: some scenes are almost OK apart from a small speed decrease but other (probably higher bitrate) scenes still don’t work. Apart from this SPMC is no solution for me since I can’t get the audio passthrough and refreshrate switch correctly working. LibreELEC is also an improvement, comparable to SPMC but still not OK on all scenes. Playing with other players on Minix gives the same partial improvement as SPMC I’m out of options. Anyone an idea?
