This collection is exposed to Kodi via http, requiring nothing more special than a web-server (my NAS) with directory listings enabled. However, I've been gifted a Roku 3810EU and wanted to play around with using that a bit. It's been a good few years since I last played with a Roku (we had one to help with monitoring and testing a few jobs back), but the interface feels as accessible as it did then.
