After a little bit of trial and error, I figured out how it works. I used v19 to test.
If you open your
guisettings.xml file you will find the settings which look like this example...
xml:
<setting id="videolibrary.showunwatchedplots" default="true">0,1,2</setting>
<setting id="videolibrary.groupmoviesets" default="true">false</setting>
<setting id="videolibrary.groupsingleitemsets">true</setting>
<setting id="myvideos.flatten" default="true">false</setting>
<setting id="videolibrary.flattentvshows">0</setting>
<setting id="videolibrary.showemptytvshows">true</setting>
Selecting one and breaking it down
xml:
<setting id="videolibrary.showemptytvshows">true</setting>
videolibrary- parent tag
showemptytvshows- tag
true- value
Which then becomes this for the advancedsettings.xml file...
xml:
<advancedsettings version="1.0">
<videolibrary>
<showemptytvshows>true</showemptytvshows>
</videolibrary>
</advancedsettings>
Then you will note that this setting is no longer visible in the Settings pages
Once others can test and confirm it works as described above, I will update the wiki page.
