I'd like to be able to stream DVDs from my Linux box but also get it to play things like youtube videos or netflix. Ideally I'd like android and iOS apps to control it as well. I'm open to suggestions.
CastagnaITs Netflix Plugin works well, but you'll lose the official Interface, if that's important to you. You might need to set up a key file (see the github repo).
The default Youtube App needs an API key but it works.
It's possible to stream Videos directly to the box from Kore on Android. Idk how this works and I'd love to know a way to do this from my Linux notebook, but I haven't had time to figure that out yet.
An alternative might be running a full Raspberry OS and e.g. stream movies from your desktop via samba or NFS.
Also have roku's and chromecasts. Roku was my preferred device for a long time but they started pushing ads so it went in a box in the closet
