Where to put home videos?

To clarify what you've done so far, you ssh'd to the server that is hosting the SMB share to check permissions. And in the Jellyfin UI you've indicated that Jellyfin, the app, can't see it, correct?

Can you open a bash shell for the Jellyfin container and navigate through this mounted SMB share's paths to verify that the container is able to see the files? If the Jellyfin container can see it but the Jellyfin app can't, we'll work it from that angle. If the container can't see it, we have to work it from that angle.
