@Cydewayz Ok so step by step:
1) Download and install jellyfin on your PC. If the installation succeeded, you'll see a triangle symbol in your windows tray (right part of the task bar). There you can click "open Jellyfin" and it should open a browser and you should be able to see all your movies that you've chosen to share. If that works, then jellyfin installation has succeeded. I dont remember if jellyfin asks to open the port on your firewall, but if not, to test things first just disable the whole firewall itself (dont forget to put it back lateron and then you should open the port, let me know if you need help with that).
2) Then put on your headset, make sure you're connected to the same network as your PC. Then open my app in the headset, click settings and put in the info.
Then you click on 'open jellyfin' and if it works, it should list all files you've chosen to share with jellyfin
If you need any help just let me know
