ListItem.Property(tvshow.dbid) will give you the base tvshow library DBID as long as you have enabled the option to retrieve Kodi database details in settings (it's an option for performance reasons for users with large libraries - so it's not something that can be forced by a skin).

xml:
<onclick>ActivateWindow(videos,videodb://tvshows/titles/$INFO[Container(ID).ListItem.Property(tvshow.dbid)]/,return)</onclick>

Is there a way to know whether the user has this option enabled so I can make this action conditional otherwise to just opens the TV show library?

Thanks.
