I'm having some issues playing this file - Journey To Space (2015) Multi 2160p 4K UltraHD BluRay (x265 HEVC 10bit) ATMOS 7.1 ESub -DDR. The video stutters a lot. Now, I was having the same problem on my computer, but figured out that I needed to install the lav filter. If I had changed the audio stream to non-atmos then the file played perfect. However, with the Atmos it would stutter. The lav filter solved the problem on the computer. Now, is it possible to put this lav filter on my UH-9? Any help would be appreciated! Thanks.
