Hi Kszaq,
i have faced a strange issue, first i have installed the version H(first to the SD card and after to USB pendrive) on my Beelink GT1 Ultimate, and everything was fine
...and after updated the version j on USB pendrive (via samba share update folder) and the videos started to stuttering the videos (played from NAS via Samba share) when the external subtitle appears.
I tried to clean reinstall the h and after J on USB pendrive, but the stuttering is occured again.
After i have tried to boot on the original microsd card (it was untouched and it worked fine before, because i have changed to USB pendrive), but the stuttering is occured on this system also
, what is good before upgraded the another boot media (USB pendrive)!
I don't understand, what is changed in the GT1.
