You can now install Tailscale on AppleTV. Tailscale is a sort of personal VPN service that allows you to directly connect your personal devices to each other over the internet. tvOS 17 added support for VPNs to run on Apple TV.
What this means in the case of AppleTV region coding:
If for example, you have a computer at home that's running tailscale, and you take your AppleTV with you while on vacation in let's say, Egypt, you can set Tailscale on your AppleTV to use the Tailscale node on your home computer as an exit node, and you'll be able to stream Hulu on that AppleTV in your hotel in Egypt normally because the traffic is tunneling through your computer back home in the US, and it thinks that's where you're located.
Normally with commercial VPNs, that wouldn't work because Hulu/Netflix/etc have a list of IP addresses associated with VPN services, and so they'd detect youre connected to that VPN and block you from using it. But in the case of tailscale, the IP address they see is that of your computer back home, so they don't think you're connected to a VPN.
This can also theoretically help get around Netflixes password sharing restrictions, because if the account owner runs an exit node on their AppleTV, and the other password sharers set their AppleTVs to use that owners AppleTV as their exit node, Netflix will think the logins are all coming from the same IP address located in one place.
If you have experience with Jellyfin and don't mind me asking, if i have Plex pass is there any reason to switch to Jellyfin? I have never even looked at Jellyfin but i keep seeing people talk about it as a Plex replacement.
If you haven't run into any concrete issues with Plex and don't mind the cost, there's probably no reason to switch.
Reasons I switched:
I didn't like it when Plex asked to control my user accounts. It allows them to cut me off whenever they want, for any reason. It also prevents me from using my own server in my own home if my internet connection drops, even if my server and my network are still working.
Plex can have issues with some VPN setups.
They kept moving more and more features that used to be free to paid accounts only.
