I have mythbusters on dvd

I am wondering how I would put my tenth anniversary 10 DVD set on Jellyfin, would I put it as a TV show or what?

You have to name the episodes to match online metadata providers. For box sets like "best of" or anniversary sets, this will mean that you have a mix of episodes across multiple seasons. And you have to name your files to match accordingly.
