Personally i tend to have 3 sources

• daily youtube videos automatically downloaded trough a script.

• dvd’s, automatic ripping machine is a piece of software to automatically helps you rip your old physical dvds. Ive recovered some great nostalgia that can no longer be obtained otherwise.

• whats this? A website? https://fmhy.net/ “Free media heck yeah” thats a weird name. It looks like a wikipedia of something, I wonder what thats all about.

You can buy music from Bandcamp. You get it drm free. There may be other sites that sell music too, but Bandcamp is the one I've been using.

You can also still buy CD/vinyl and rip it yourself.

You need to host Jellyfin on your own server. For example, you can get a micro pc and attach a hard drive to it with N terabytes of your legally acquired movies and tv shows.

Getting it working right is a pain (I keep running into problems where it stops working, or the metadata is wrong, it forgets how to access the drive, and so on). You also need to ensure it has an IP address to access it from afar, and set us SSL encryption if you want secure access from afar. Expect to put aside several hours to set it up, and then several more to fix it when it breaks inexplicably days or months down the line.

Then you can connect to it from your browser directly or via the jellyfin app. Apple TV even has a jellyfin app, so I can watch from my parents' TV setup. You can set things up so that different users can access different shows even.

That's up to you. It can be from anywhere. You can buy DVDs and rip them, buy digital downloads, or rip DVDs from the library or friends. You can also go the piracy route and find torrents or direct downloads.
