i hope u r on latest firmware 2.1.1.

native player can read/play DVD video_ts folder.
u use media center, not file manager.
when it plays, u use menu button of remote to change chapters, playlist, subs, audio tracks, etc.
next/previous video, rewind/forward works too.
however, there is no full menu like playing with DVD player.
himedia has put in good work to do full menus for BDMV but has dropped that for DVDs.

use of kodi is not as good.
it does not read the video_ts folder; u need to go inside to select/play the individual VOB track.
the same happens when u use mx/mx pro player.

kodi player is not optimal with q10pro.
local playback or online streams, the best audio u can get is DD (AC3) and DD+ (EAC3).
dts and others can be transcoded to DD only.
to do that, u go to system and turn on all 4 options under audio passthru.

if yr box was purchased outside china or classified as "international version", u can use futeko firmwares.

full menus for 1080p/2160p bdmv m2ts and bdmv iso works good.

this, u dun get with most boxes.
