Thanks a bunch for the response.
Please understand that this part of IT is new to me but I do find it and the possibilities exciting
Regarding the audio, I found an audio setting where the audio was going out the HDMI port. I have the RPi running to a dumb monitor with a sound board, so I set the audio to be analogue and the sound works now and I've tried several formats.
Thanks for suggesting to increase the wait time some. That did work.
I saw a Youtube video about installing LibreElec and at the end he ran nplayer on his phone and was able to watch a different movie from what LibreElec was playing. because I now have an IP, I tried it and it works. Sadly, I can not find nplayer for my Kindle Fire. But, I was able to find Archos Video and it was able to find the LibreElec box and play the videos stored there via UPnP. Archos Video seems to be a little jerky so I may have to increase the buffer size.
Yes, maybe LebreElec isn't running all of these apps but it does seem to make the files available.
Now I need to start borrowing some more devices to see how many I can run before desegregation starts.
I'll let you know what I find.
Just now realized, to make this work where there is no Internet or network, It has to be the DNS so the other devices have an IP to link to.
How do I set LibreElec OS up as a DNS when there is no DNS?
