hey guys, sorry for my English
i'm a Chinese user, just bought a ugoos am6b-plus a few days ago, which is an android tvbox probably can playback fel dolby vision and dolby atoms, sounds great, the firmware is o.5.4, the setting DV can also tv-led and lldv,afer these days test, it can playback hdr10, dv profile5、8（dv+hdr10）、7（mel）as DV perfectly(mkv,mp4) in all the media player software include Kodinerds(19,20,21)、fandango's kodi-in-hdr(19,21).
but when playback some fel p7 mkvs use kodis, in some movies like "godfather, top gun, mission impossible" ,especially "wall-e", it video hangs,freezing but audio still play, may in few seconds come back, but I found use exoplayer in emby, it could playback these movies smoothly ,just in ⏪⏩，my tv goes black in a second and came back continue playback like normal , the nova player better than kodis,and worse than exoplayer in emby.
use quietvoid dovi build, it playback from begging no issues, but after ff/rew or playback in middle the video may frezzing also.
@Maven do u have any ideas?
