hi all i have these problems with my z9x pro the hd connected to the usb 3 port can be seen with all the applications installed by default. I installed vlc and opera browser and other apps with which it is not possible to see the hd connected to the usb 3 socket. I activated the internal samba server of the zidoo and when I look at the shared files, it only shows the internal memory and not the hard disk connected to the usb 3 port. When I watch movies with the ziddo software, every scene changes the lighting after 1 or 2 seconds, as if the dolby vision metadata arrives 1 or 2 seconds late. When I look at it with vlc it can be seen perfectly, but unfortunately vlc does not see the hd connected to the usb 3 socket as I have already said
