[Myth]

As you add new content to the various source folders, do the playlists automatically pick them up?

Yes, as soon as they have been scanned they will appear in the proper category. What the playlists do is simply filter the regular library with the defined rules. So as soon as you update your library, so will the playlists.

Is there any problems with the library and scanning content?

Nope, using these playlists changes nothing. Except that i must now update my library by going to settings->video files, instead of movies->files. But in the end I get the same window. And if you have automatic library updates, you don't even have to do that.

How do you scan in your more obscure files in to the library? Did you create nfo files manually or have another solution?

Suppose it depends on what kind of obscure files you are talking about. For anime shows that aren't found on thetvdb.com, i go and add them on the site. If it are movies that actually don't belong on those sites I'm not sure what I'd do. Didn't encounter these situations yet.

Also is there anyway that you can lock or password protect certain categories?

When I was trying to find out how I could create these categories I did come across many people recommending to use different profiles instead. Using profiles you can deffinatly use a password. Don't know about any tricks for the solution I used though. It's not something I have looked into.
