Hi, i have KI pro with S905D. I am first used LE as 8.2.2.2. I will say first thanks to adamg and kszaq. My tv box had last rom firmware from july 2017 and now from 30. october. I dont had never trouble with audio-video synchronization in these original rom, ... but with equal videos i have audio-video synchronization (mp4 codec) bug in LE from 8.3.1 (i dont see these troubles in ver. 8.2.2.2, but maybe was also).
