I have a box full of these devices and I have tried a few builds and Im having issues with the pvr iptv simple client with network streams. seam to be crashing or having system lock ups. Tried the libreelec 16 and works great even locked up once but rebooted and started playing again.
I tried all the 9.80 Orange Pi H3 builds and the 9.1 Orange Pi build compiled by Dejan_ his one seemed to be the best but once i loaded the pvr iptv simple client it lagged and froze.
