Regarding Tritium H3,
I tried a few things yesterday, installs fine, my needed add-ons work, although the streaming buffers a lot. I don't know if it's related to the Tritium H3 or the mpeg-dash stream. We always had problems with these streams, but no freezing or repeatedly buffering. When I switched back to my khadas vim1 running leia everything was OK'isch using the same add-on.
Couldn't log in with samba, but maybe i didn't try enough. Before shutting down the device I checked the LE settings and there seems to be a choice now to login with or without pasword. but I didn't try it anymore. I know it nevers gone happen but a nfs server is way more trouble free.
