How does ethernet to the attic help with this?
I think the only concern might be subjecting the HDHomeRun to attic temperatures in the summer.
I'm also long-term concerned about how Plex as a company is moving away from its server product and towards FAST (free, ad-supported TV), a feature I almost never use. I'd love to see Jellyfin get some equivalent features.
I'm also quite displeased with plex's new direction. Would love to see some real competition.
