Happy to buy hardware if needed. Just trying to avoid large streaming services abhorrent business practices.
You can share your plex library. So the person can stream from your files. Pretty easy to set up.
This is what I do. Plex server with storage at home and brother just connects via his app built into his TV. They just text if they want a certain movie or TV show and I add it.
I have a similar setup. The only strange thing is that one house always seems to have buffer issues while the rest don’t (they’ll start a show and it will buffer every few minutes). What would you recommend in that situation kind stranger?
A better ISP or a better WiFi connection. Most of the time it is bandwidth related. Maybe let them manually select a lower quality stream.
